To Recycling Today’s Baler Guide

e is one piece of processing equipment central to a recycling operation, it has e the baler. Without its ability to compact material into dense, easily stacked

packages, recyclers simply could not move their material cost effectively. It is also a piece of equipment that crosses nearly all secondary commodity markets, including paper, cardboard, plastic, used beverage cans, and ferrous and nonferrous metals.

This guide is intended to help recyclers make a more informed decision about what type of baler best suits the needs of their businesses. Included in the guide is a detailed overview of each type of baler, including how it works, expected operational considerations, capacities and general price ranges.

While processors and manufacturers who contributed to this guide had a wide range of comments, the editors of Recycling Today tried to include only those that represented a consensus of opinion or that were based on fact. For instance, in the area of baler capacity, nearly all recommended buying more baler capacity than currently required. By doing so, the processor can ensure room for growth, and also pick up volume to help weather depressed markets.

The last article in this guide is an overview of baler options, including conveyors, fluffers, pre-press devices and more. These items are all designed to make the baling process more efficient.

Following that article is a glossary of baler terms we hope you will find useful. In the back of the guide, you will find a directory of all the known baler

manufacturers and exclusive distributors operating in North America. These listings indicate the types ofbalers each company makes or sells, alongwith addresses, phone dnd fax riuinber s dIld Iriterriet arid E-mail dorrmirw.

Finally, we would like to thank the numerous baler companies and processors that provided input to this guide. Special thanks go to Badertscher Communications, Marion, Ohio, for providing the cover photo of a two-ram extrusion baler in operation at the recently built E.L Harvey & Sons Inc. material recovery facility in Westboro, Mass.

realm of horizontal, single-ram balers, there are two basic types of models: the end extrusion baler and the closed-end baler. The horizontal, single-ram sion baler is a high production baler, while closed-end models are geared more

toward lower production. Most closed-end models are limited to a few bales an hour, while extrusion balers can produce up to four ames that number.

One manufacturer says that “processors should be confident if they really only need a low-capacity baler. Closed-end balers have their place, but processors should not put themselves in a position that they will be regretting soon after their purchase.”

But others point out that even if processors expect to be processing at or slightly above the limit of a closed-end baler, they should consider making the investment in an extrusion baler. Many do so simply to avoid the hassle of having to manually tie closed-end bales.

OPEN-END EXTRUSION In an open-end, horizontal, single-ram extrusion baler, a bale is made by compressing and squeezing material through a long extrusion chamber. After the first bale (called a plug bale) is made, the subsequent bales are made by pushing material up against the back of the forward bale. Since the extrusion chamber is open-ended, the first

bale will be somewhat looser than the other bales because it only has the ten- sion force of the wire to bale against (in addition to the side forces), and not another bale.

“These balers are perfect for operations that are moving large amounts of material like cardboard or paper,” says one manufacturer. “It is not designed for making one bale at a time. The material has to keep coming to make it a very efficient baler.”

The single-ram extrusion baler is best suited for baling all grades of paper and old corrugated cardboard, and it can even bale used beverage cans, steel cans and plastic bottles.

Generally, a processor can expect to get rates of about 10 to 15 tons per hour for UBCs; 20 to 25 tons per hour for OCC; 25 to 30 tons per hour for mixed paper; and 45 to 50 tons per hour for

newspaper. Rates will vary according to the size of the baler, feed flow and baler options. There are even some extremely large balers that can bale higher throughputs - as much as 70 tons per hour for mixed paper.

Single-ram extrusion balers can cost anywhere from just under

pending on the model and its rated capacity. “You can buy a basic small model, oraverylargeonewithveryhigh output,” says one manufacturer.

Bale sizes vary between models, with widths from 33 inches to 43 inches; heights from 28 inches to 43 inches and lengths as short as 12 inches, or aslong as the wire will hold and the bale is manage- able. Some processors have produced bales 8 feet in length - the width of a shipping container.

Also, because an operator can vary the lengths of the bales, a bale of one material can be finished off and a different bale of new material started behind it without risking contamination. There

are two ways to accomplish thisl. The first is to make a smaller bale with the leftover feedstock in the charge box; the second is to create an oversized bale by adding the material to the last bale.

These types of balers are extremely flexible, according to operators. One processor says his firm bales seven different types of material and may switch grades several times a day without a hitch. “It’s so easy to switch materials because, no matter how much material is left over, you can still compress it, tie it off, and get on with the next material.”

BOLLEGRAAF THE BALER THAT REVOLUTIONIZED THE INDUSTRY WITH THE ORIGINAL PRE-PRESS FLAP

For 35 years Bollegraaf has been making balers that have defined quality in the recycling industry - first in Europe and now here as well. So, i t was no surprise when Houghton Waste Paper in England challenged us to build the largest, strongest, highest capacity baler ever.

The HBC 140 can process 60-80 tons per hour and is 25% faster than the HBC l l O F , previously our largest baler. We are now offering the HBC 140 as the largest member of our baler family, which includes models of varying speeds and capacities. But the best thing about the HBC 140 is not that it’s the world’s biggest baler, It’s that it’s a Bollegraaf.

All Bollegraaf balers are fully automated, built to last and feature our famous pre-press flap - the technology that revolutionized the baler industry.

Thanks t o the pre-press flap, no operators are needed for our balers, they are extremely energy efficient and have very low maintenance costs, Which is why, in the long run, our balers are not only the best, but also the least expensive.

Because bigger isn’t always better. Just when it’s Bollegraaf. So call your Van Dyk Baler Corp. sales rep to find out more about Bollegraaf balers.

ing material grades to maintain proper baling pressures and reduce stalling. It is considered an energy-efficient design because the main force is concentrated at moving the material through the extrusion chamber, which squeezes and gives accordingly. In addition, a single- ram baler needs to power only one ram instead of two.

SINGLE-RAM LIMITATIONS Despite all these strengths, single-ram extrusion balers also have limitations.

The first is that bale lengths can swell and differ by several inches, and this can be a concern when shipping. For instance, suppose the bale length counter (formally called a lamination counter) stops at 68 inches after the last stroke, and the designated bale length is 72 inches. If the next charge compresses 5 inches of material into the extrusion chamber, the counter will trip at 72 inches but can’t begin to tie off the bale until the stroke is finished. At that point, the extra inch of material has already passed the tie-off point, and the bale length will be 73 inches for that particular bale.

One way to combat this is to install a photo eye that will automatically control the amount of material entering the charge box and reduce bale swelling. By adjustingthephoto eye, an operator can

If the bottom material is denser, it will tend to expand more, swelling the bottom of the bale and causing the bale to assume a trapezoidal shape and to curve slightly. Using a fluffer will also help eliminate this problem.

The second limitation involves the types of materials that the horizontal extrusion baler can process. While this type of baler processes paper and OCC efficiently, it may not be the ideal baler for UBCs and plastic bottles, and it cannot bale metal extrusions. When compressed, extrusions can puncture the next bale, causing it to fall apart. In addition, the fingers that guide the wire for tie off may get bent.

Processors add that single-ram extrusion balers are not best suited for pro- cessingplasticbottles because the bottles can more easily expand (known in the industry as “regaining their memory”). This is because only five wire straps of annealed wire are used, and that type of wire is more ductile than the high-tensile wire used in two-ram balers. But proponents of single-rams simply say you can

tolerances to ac. commodate these materials.

Finally, a single-ram baler has a smaller hopper than a comparable two- ram model. This is because the hopper is limited by the width of the bale being made. Hopper widths can vary from 33 inches to 43 inches, and lengths may vary from 50 inches to more than 80 inches. But with a two-ram, the hopper can be as long as the length of the bale, so these hoppers can be as large as 60 inches wide by 110 inches long - overall, better able to accommodate more bulky material.

While several balers use pre-press doors or flaps that push material down below the shear blade to prevent jam- mingand have rams that travel on wheels, there is a new type of single-ram extrusion baler that uses a pre-press ram from the side of the hopper. This unit has the benefit of a large hopper that is 80 inches by 70 inches. This baler has been classified, actually, as a twwam extrusion baler, with the second ram having compression force equal to the main ram.

“This gives you the best of both the two-ram action and the extrusion chamber,” says the manufacturer, “resulting in denser, more even bales and higher throughput.”

CLOSED-END BALERS A closed-end, horizontal, single-ram baler is considered a low-capacity baler that can be used to bale OCC, paper, plastir lJBCq, steel cans and other light metals. The baler’s lower capacity is due to the lack of a long, continuous extrusion chamber and the use of manual tie-off systems.

Most manufacturers recommend this type of baler for an operation that is

or about 4 to 5 tons per hour. Single- ram, closed-end balers usually produce shipping bales that are 30 inches high by 45 inches wide by 60 inches long.

Costs for single-ram, closed-end balers are between $20,000 and $100,000.

In this type of baler, a single ram

processing about three bales an hour, -

compresses material into a baling chamber and against a door, and then the bale is tied off manually. At this point, the back of the chamber opens, releasing pressure in the forward direction. As the baler continues to operate and more material is fed into the chamber, the finished bale is slowly pushed out with each cycle of the rani.

Another model simply uses an ex- tended ram to eject the bale without having to add more material behind it. When the tied-off bale clears the door, it can be removed with a forklift. The door then closes, and the sequence continues.

On a closed-end baler, the door can open to either side, or raise vertically to provide for faster operation.

In a side-eject baler, material is baled into a chamber just like in the previous configuration, but this time pressure along the ram axis is exerted on a fEed wall. Unlike the door-eject method, material is not constantly fed behind the finished bale. Instead, pressure is re-

lieved from the bale in three directions to achieve bale ejection out of the side of the baler after it is tied off. First, the ram is retracted, eliminating the end force. Then the side door is opened, relieving the side force. Finally, the hinged top of the chamber relaxes, relieving the vertical force on the bale.

When the pressure is relieved in all

three directions, a hydraulically-powered server island at the base of the baling chamber protracts, carrying the bale with it. The island also allows the forklift operator to easily position the forks under the bale and eliminates the need for a separate pallet to be positioned at the exit point.

Tieoff methods for both side and end- ejectbalersareusu- allymanualandcan be either top tie or side tie. Some manufactures have special guides to help speed up the tying process.

Since bales are made in a closed baling chamber, . they are extremely uniform. “You get very square, exact and dense bales,” says one manufac-

companies that produce them. In this type ofconkguration, one ram compresses the material against a wall and into the path of a second ram. As the second ram pushes the material out, it forms a bale, is tied off and continues out of the baler through the ejection nozzle.

DURABLE DESIGN Due to its design, a two-ram baler has a reputation of being tough and able to handle many high-volume baling applications. Because of the dual-ram action, the two-ram normally has a larger hopper and corresponding charge box than a single-ram baler. This allows the baler to accept more bulky material. Single-ram balers are limited by the width of the bale, which is normally 43 inches, so the single-ram hopper can only be that wide.

In a two-ram configuration, the width of the hopper is also the length of the bale, which is normally 60 inches (unless the two-ram baler is a narrow-box model, which

There are currently two methods of tying off a bale - on the side or on the top. In a top tie configuration, banding is wrapped around the bale from front to back, under the bottom of the bale and over the top in a vertical fashion. In this method the banding is tied off or knotted on the top of the bale. In the side tie method, the banding runs around the bale in a

only has a 43-inch wide hopper). There- fore, two-ram baler hoppers can be as large as 60 inches wide by 110 inches long. Bale size is normally fured, with the most common size being 45 inches wide by 30 inches high by 60 inches long.

The larger hopper also allows the processor to use wider and faster conveyors to feed the baler. Many manufactures say that this eliminates the need for a fluffer or shredder to pre-condition the material before it enters the charge box, providing cost savings. More energy savings can be realizedif apre-press is added to push material below the shear blade.

“This is an add-on that has been proven on single-ram balers for years,” says one manufacturer. “Now we are taking those proven technologies and applying them to two-ram models.”

Since the main compression ram in the two-ram baler bales against awall and not against another bale as in a single- ram extrusion baler, proponents claim that the two-ram makes a denser bale. “The ram of a single-ram baler simply does not go in far enough,” says one manufacturer of both single- and two- ram models. “And there isn’t a wall to bale against.”

Another advantage manufacturers point out is that two-rams make more precise bales than single-ram extrusion balers. “Bales made with a two-ram load betterthanthosefromasinglerambaler,” says another manufacturer.

Many processors agree. “We have many types of balers,” says one large processor, “and with my two-ram, I don’t have to worry about the bale sizes - they are perfect every time, and that makes shipping a snap. With our single-ram

horizontal fashion and is tied on the side of the bale. In both methods, the banding is perpendicular to the laminations, but on different planes.

Side tying is mainly used with single- ram extrusion balers and for single-ram closed-end balers, and top tying is used mainly for two-ram and verticle balers.

Top tying, single-ram extrusion balers are now being offered. Proponents say these result in increased safety because the knot is on the top and therefore out

bales, it is always a challenge when it comes to loading them because the sizes differ.”

BALING MORE GRADES Processors who purchase two-ram balers say they buy themmainly to bale material that simply can’t be baled in a single-ram baler, or because material bales better in atwo-rammodel. These processors point to UBCs, steel cans, plastic bottles and extrusions.

“You can bale plastic bottles andUBCs in a single-ram, but you can bale them better in a two-ram,” says one processor. “We bale a lot of paper, and we have single-rams for that purpose, but we also bale a lot of plastic bottles, and we are using the two-ram baler to do that.”

Baling plastic bottles, particularly, seems to have the edge in a two-ram, according to processors. “We have baled plastic bottles in a single-ram and there is just too much e x p a n s i o n

of the way of someone who may rub against the bale and catch the knot on their clothing. They also claim that top tying keeps the bale more intact.

However, proponents of side tying for single-ram extrusion balers say that since the wire is on the side, it won’t catch on the bottom of a forklift. Also, with top tying, a pit has to be dug out under the extrusion chamber to allow clearance for the fingers that carry the wire.

Since a two-ram bales against a wall, this problem is avoided.

Two-ram baler capacities can be as high as 55 tons per hour for paper, 15 to 30 tons per hour for OCC, about 10 to 16 tons per hour for UBCs, and 4 to 12 tons per hour of plastic bottles.

SIZE LIMITATIONS While creating identically-sized bales is an advantage of a two-ram baler, it is also a limitation, because it is not easy to adjust the size of a bale, and that can be important if the mill changes its require- ments. Also, if there is not enough material to make a bale, the operator has to make a contaminated bale, clean out the baler or wait for more material, say processors.

However, several two-ram manufacturers have found a way to solve this problem. These companies have installed a door near the end of the ejection

nozzle that can close to separate material and hold a bale in dace so that more

(continued o n page 18)


Two Ram (continued from barre 16)

“Bale size diversity has traditionally been a limitation of the two-ram baler,” says one manufacturer. “Now, two rams can offer size flexibility, too.”

Another limitation can be the operation of the baler itself. While manufactures say two-rams are designed to run in the automatic mode, processors are say- ing that they usually have to have an operator nearby to address jams and other concerns.

COST TO OPERATE Overall, the cost of a two-ram can be anywhere from a low of $100,000 to a high of $500,000, depending on the model. Comparing asingle-ram and two- ram with the same output, you will probably pay more for the two-ram.

Operational costs of a two-ram baler should also be considered. The two-ram costs more to operate because of the

additional rani and because of the greater baling pressures required. But proponents of the two-ram say that, overall, operating costs are comparable to that of a single-ram extrusion baler because the Dro-

Vertical balers, which are highly portable, are

balers, also called downstroke balers, use a single ram to compress material top to bottom. These balers are highly portable and can produce a wide range

sizes. While many produce bales that are smaller than those made by tal balers, there are large vertical balers that can produce a shipping bale.

any operations want the larger vertical baler to get a mill size bale of cardboard, for instance, which weighs more than 1,000 pounds,” says one manufacturer.

While vertical balers are common in grocery stores and other businesses that need to bale material such as old corrugated cardboard, cans or plastic bottles, they are also found in small recycling operations and even in scrap yards where they are used to bale extrusions, radiators and other scrap metal.

“That’s the beauty of avertical baler - you can balejust about anything in it,” says another manufacturer.

A vertical baler can cost from about $5,000 to as much as $40,000. Those that make a shipping bale appear to be the most popular models, and some can even make a bale as large as 44 inches wide by 48 inches high by 75 inches long. Baling capacities can reach up to about 4 bales an hour, and some can produce bales of OCC weighing up to 2,000 pounds.

Some companies also manufacture customized vertical balers with as many as (continued on page 22)

Vertical balers have a front door that opens so that the bale can be tied off manually and removed. Some models have slots in the door so that the bale can

be tied off without compromising the integrity of the bale. Other models have auto tie and hydraulic bale ejection.

Finally, a potential purchaser should consider the height of a vertical baler.

These types of balers are mainly used indoors, so ceiling clearance is a consid- eration. There are low-profile vertical balers on the market that canbesqueezed into tighter spots.

Ferrous balers and shearhalerllogger

combinations are designed slightly differently

than other balers in order to handle tough scrap.

iiboth portable and stationary models, and some are combined with a guillotine shear and have logging capabilities. These shear/baler/logger combinations offer processors a great deal more versa- tility.

While a two-ram baler can bale light ferrous, it cannot handle the heavy materials like a ferrous baler can. Ferrous balers differ from two-ram balers in several ways. First, they are built more ruggedly to handle scrap metal; sec- ondly, they usually have a long charge box that also serves as the baling chamber; and finally, bales are not tied off.

FERROUS BALERS Ferrous balers can be categorized as two- or three-compression or three-ram. In a two-compression model, one side or wing door squeezes the material along with the main ram. In a three- compression model, both sides or wing doors squeeze the material along with the main ram, or one side, a top lid and the main ram. All rams and compression tops and sides are hydraulically operated. A three-ram model has a main compression ram, another one that compresses from the top, and a third one that ejects the bale. Material is fed into the baler with a crane.

Ferrous balers produce bales that are normally 24-inch cubes, and are

about 60 to 70 pounds per square foot ~~

in density. Some things to consider when buy-

ing a ferrous baler are portability, power units, crane features and pre-

A ferrous baler can be portable or stationary, and there are distinct reasons for buying one over the other. Benefits of a portable ferrous baler include the ability to take the baler out of the yard to where piles of scrap are located. In this configuration, the baler is powered by a 150 to 200 horse- power diesel engine. The portable model generally costs about $135,000 to $255,000.

Ferrous Balers (continued from bape 24)

Stationary models are ideal if the baler is generally going to remain in the yard or operate indoors. The stationary model can be operated electrically and that’s a plus with many processors because it means low noise andless air pollution. In addition, processors don’t have to worry about diesel fuel. Because of the motor configuration and the lack of wheels, the stationary baler is slightly less expensive than the portable model.

An integrated crane - one that is attached to the baler - is an option that processors should investigate thoroughly. “We don’t normally think about it, but there is going to be an operator in that crane cab all day,” says one manufacturer, “so the processor should at least consider the comfort level of that operator.”

Creature comforts such as air conditioning, heat, ergonomic controls and

could limit the productivity ofthe baler if it is solely relied upon to feed the baler. “It’s okay if youare takingapor- table baler out to process about 40 to 50 tons ofmaterial,” says one processor, “but ifyou expect to process more than that, then you should be using a separate, support- ing crane.”

Another area to consider is the size of the charge box. Most are around 12 to 15 feet in length. The bigger the box, the bigger the target for the crane operator.

PRE-STAGERS In order to increase the productivity of ferrous balers, manufacturers have

simply a comfortable seat are items to consider.

The crane should also have an ad- equate reach - somewhere between 20 and 25 feet. A longer reach means less double handling of material. In addition, look for crane cabs that rise up slightly for a better viewing range.

While having an integrated crane seems ideal, some warn that having one

transport on portable balers. Front- mounted tips pans, however, do allow for increased portability.

The second way is by using a rela- tively new method called a pre-hopper. This device pre-stages scrap above the baling chamber. When it is ready to be baled, a chute opens and the material falls into the baler. The chute closes and is ready to be loaded once more. Be- cause it is gravity operated and above the baler, this type of pre-stager can be added to a portable baler.

SHEAR/BALER/LOGGERS A choice that is becoming popular with ferrous scrap processors is the shear/ baler combination, because it gives a yard more flexibility. These machines have a shear at the ejection end with 300 to 1,000 tons of shearing force. In this way, when shearing needs to be done, material in the hopper can simply be pushed by the ram in the form of a log and through the ejection opening as the shear does its work. If baling is the priority, the baling capabilities of the machine can be used.

Processors and manufacturers warn that shear balers are not for everyone, but are targeted toward smaller yards. And high-capacity operations should not rely on one alone to meet their processing needs, because the shear/baler can be overwhelmed easily. Shear/balers are normally recommended for yards that are processing about 5 to 10 tons of material per hour.

Processors also have to be sensitive to the narrow throat of a shear/baler, which can limit the speed of shearing.

Some shear balers have asliding door that goes in front of the shearing knife so that the baling pressure is against the door and not the knife.

Affordability, however, is amajor selling point of a shear/baler. Models can be bought for as little as $300,000 - far cheaper than buying a baler and a shear separately. Some shear/balers can cost as much as $1.5 million, depending on capacity.

Another capability of some ferrous balers is logging. A log is a long, soft bale that is made to compact scrap so that it can be more efficiently transported to a shredder. Logs are usually 4 to 6 feet in length and are about half as dense as ferrous bales. Look for balers that can easily switch the baling pressure from one processing method to the other.


Today's balers use a variety of devices and

methods to help prevent jamming and keep

productivity high.

operation of the baler by the.operatoris a factor, more balers are being designed to operate hands-free. Designers have added several types of antijamming devices, including pre-presses that push material down below the top shear blade. They have also designed saw-toothed and staged shear blades that cut material off more efficiently, and have installed bale release mechanisms and specially designed extrusion chambers that open up or relax when the baling pressure exceeds a certain force.

In the area of increased productivity,

manufacturers have installed other options in balers to increase efficiency, such as auto tie systems, photo eyes, fluffers and side compression pre- presses.

HIGHER PRODUCTIVITY At the feed intake stage, a fluffer can be added to ruffle the material before it enters the charge box. The purpose of the fluffer is to mix the material so that it settles more uniformly and without air pockets. A shredder can be included as well.

Several companies are now employ- ing a photo-eye system that automatically detects how much material is in the charge box so that the proper amount

of material will be baled and the bale will be the correct size.

Pre-presses have been added to push material down below the shear blade, and some even lock in place. One manufacturer has its ram on wheels because there is no shearing action.

Another type of pre-press has been developed to compress material from the side in the charge box in single-ram extrusion balers. The side compression ram enables the baler to have a larger hopper so that more material can be compressed per stroke. The manufacturer says this results in a combination of the benefits of the single-ram extrusion and the two-ram baler.

Finally, many balers now have auto-


matic tying systems instead of manual ones. On single-ram extrusion balers, the auto tie system interjects fingers or needles through the extrusion chamber and then ties off the bale in front while setting the wire for the next bale in line.

In two-ram balers, the auto tie system simply positions the wire so that as the second ram moves the material, it can be tied off correctly. Two-ram balers are even offering special doors that can clamp a bale as it is being ejected so that more material can be added to it, giving the baler the ability to make oversized bales.

Other add-ons include cross-tie systems for single-ram extrusion balers so that material such as plastic bottles, which tend to expand and unbale, can be better held in place.

Finally, the processor should think about how material is going to be con- veyedinto the baler. There are numerous types of conveyors and methods, and it is important to discuss those options with the baler manufacturer before purchasing.

GETTING OUT OF A JAM There are two common types of baler jams. The first occurs in the baling chamber when too much material is compressed and the ram cannot eject the bale. What manufacturers have done to address this is to add a release mechanism that retracts one of the walls of the chamber enough so that the bale can move forward.

The other type of jam occurs in the charge box when material gets caught between the ram plate and the stationary shear knife. There are two innovations that solve this problem. One is making the shear knife saw toothed or in stages, so the material hits parts of the blade at different times, effectively cutting the

ales are shipped by trailer, railcar and container, and it is important to know the dimensions and weight restrictions of each if you are considering shipping by a new venue.

B Truck trailer -the average-sizes of truck trailers are typically 48 feet by 8.5 feet. Other sizes are 45 feet by 8.5 feet; 45 feet by 8 feet; 48 feet by 8 feet; and 53 feet by 8.5 feet. This last trailer size is generally not used used for transporting recyclables, according to shipping companies. The maximum allowable weight of a truck - including cargo - is 80,000 pounds, as set by the Department of Transportation. The typical cargo weight is between 40,000 and 45,000 pounds.

Railcar - boxcars are generally 50 or 60 feet in length, 9 feet 6 inches wide and about 10 to 13 feet high. There are two payload limitations for railcars. The first is called Free Interchange, meaning the railcar and its load cannot exceed 263,000 pounds. Any railroad that is a member of the Association of American Railroads, Washington, has to accept a Free Interchange load. The other is called Controlled Interchange, where the combined railcar and load can be as high as 286,000 pounds. In Control Interchange, the receiving railroad must give the sending railroad prior permission to accept the shipment. A typical railcar weighs 70,000 to 75,000 pounds, and the average railcar load weighed 65.3 tons, or just more than 130,000 pounds, in 1995, according to the AAR.

Container - international and domestic shipping containers are typically 20 feet by 9 feet; or 40 feet by 9.5 feet or 9 feet. There are also containers 45 feet by 9 feet. Domestic intermodal container sizes are 48 or 53 feet long by 9 feet wide. These are limited by the over-the-road weight restrictions mentioned in the truck trailer segment.

down enough so that the ram can push through the chamber.

Many companies arenowaddingthese push-down devices simply because it

increases the efficiency of baling. A lot of energy is spent when material needs to be sheared off at the shear beam. If you can push that material down, you save money in electrical costs.

The pre-press in some balers can also be programmed so that when it receives a signal that the baler is jamming, the ram retracts and the stamper comes down and pushes the material below the shear beam. Onboard com- puters are doing a better job of auto-

material. The other method involves a prepresslid, sometimes calledatramper or stamper, that pushes the material

matically sensing when a j& is occur- ring, so they may instantaneously retract and re-cycle the ram without the

operator even knowing it. Pre-presses are also important for safety reasons, say manufacturers, because they keep people out of the baler.

Although these devices are not new, they have received renewed attention lately because they are now being added to two-ram balers, whereas they were previously only common on one-ram systems.

Some companies employ a release mechanism that bows the middle of the extrusion sides outward so the bale can move forward. One company has recently developed an “H” style extrusion chamber that compresses the bale from the sides and the top, but when a stall conditionis about to happen, the mechanism releases both sides and the top,

enabling the bale to proceed. The benefit of this is that denser, more even bales can be made. The chamber is able to hold onto the material longer, and is

However, some argue that the pre- press can cause uneven densities in the charge box, making the ramming force less effective and producing a bale that is actually less dense than one made without a pre-press.

Once material is baled, it must be tied off properly to ensure that the bales will stay together. The most common material used for banding bales is wire, and the two most widely used types of wire are annealed and high tensile. When comparing two wires of the same diameter - one annealed and one high tensile -the annealed will be more ductile or have the ability to elongate more than the high-tensile. That means it will tend to flex better under loads.

As for other characteristics, high- tensile wire is galvanized, while annealed wire has a layer of scale on it and a rust prohibitive coating.

Prices for wire differ depending on the type, gauge and quantity purchased. One of the most popular types of wire is a 12 gauge high tensile brand. For 100 pounds, or about 3,367 feet, the cost is about $35. Annealed wire of the same gauge and quantity is generally a few dollars less expensive.

Another way to receive baling wire is in the form of bale ties. These are normally cut in 14- to 20-foot lengths and are used in balers that have manual tie systems. The bale tie comes with a loop pre-formed on one or both ends, depending on the application. Bale ties also come in annealed and high-tensile wire, but in this case the high-tensile is produced to be more ductile. This is because the wire has to be flexible to handle and insert in order to manually tie off the bale.

Bale ties generally costs about $5 to $8 dollars more per 100 pounds than the high-tensile coiled wire of the same gauge.

There's an ongoing debate on which type of baler has the highest wire costs, but one processor put it this way: " 1 am using more straps on my two-ram bales, but those straps are going around the bale's width, which is only 43 inches. The five straps that are going around my single-ram bales are going around the bale's length, which is 72 inches. So, we have figured that our wire costs are about the same for either process."

'Build a better mousetrap, and they'll beat a path to your door.' It's an old line, but it still holds true. For mousetraps and balers. And that's the basis of the idea behind our new T-REX'".

Extra-large 80" x 70" hopper easily accepts large 1

T-REX combines the best features of a two-ram baler, a single-ram extrusion baler, and the pre- press flap. The result -the world's first fully- functioning two-ram extrusion baler. If you need a horizontal baler to process large volumes of recyclables, this is the one you need.

hydraulics, and free-floating 3 I

extrusion chamber for easy grade changes. i__ --

Here's what makes the T-REX so unique:

Uses both rams to produce dense, consistently even bales.

Fully-functioning pre-press ram has a simple lever-action toggle system that increases compression and virtually eliminates binding and stalling.

Revolutionary new balers, or mousetraps, don't hit the market every day. This is one of those times. The innovative T-REX - it's a whole new class of baler. For a free copy of our T-REX video, or more information,
