INTRODUCTION

SERVICEOur commitment to outstanding service has been the main reason for our consistent growth since 1977 as we recently built a much larger manufacturing facility to maintain this level. When it comes to service, we have one goal — to provide the best in the industry. Absolutely no one ships hot jobs quicker. We can do this by stocking the raw materials we need and operating only one full shift in our manufacturing plant. This allows us the

key equipment and material when hot jobs are ordered. We have a full engineering staff on hand capable of performing

questions you may have.

QUALITYWhen it comes to quality, we will put our products up against anyone in the industry. Prior to manufacturing, all custom conveyor designs must pass a computer stress analysis covering

shafts. On request, this information can be provided at time of quotation. Our components are manufactured in-house allowing us to keep tight reign on quality control and must pass a full inspection prior to shipping.

PRICEOur stainless conveyors are built entirely under our roof. You will not pay multiple markups for subcontracted parts. We handle complete manufacturing and engineering functions through our facility in Cedar Rapids. This means that, even with industry leading standards for quality and service, we can still offer very competitive pricing.

REFERENCESOur customer base has grown over the years primarily by word

opportunity to work with companies such as:

Again, thank you for the opportunity to get to know us better — we are very proud of the work we do and look forward to working with you.

in stainless steel screw conveyors, presses used in a variety of industries. The cornerstone of our success for over three decades has been our ability to provide a quality product at a reasonable price in a timely manner.

Contaminable materials, such as certain chemicals and food additives, require the use of sealed end bearings and hanger bearings of wood, nylon or other dry operating type. Trough covers should be tightly sealed and easily removable for frequent cleaning and all the internal welds that contact the material may require polishing to eliminate material entrapment.

TROUGH END PLATE WITH FOOT: Our most common end plate design for U-troughs. The integral foot design eliminates the need for saddles or feet at the screw conveyor ends. Also provides additional structure for support of drive mechanisms. Can be ordered with pedestal bearing mounts.

TROUGH END PLATE WITHOUT FOOT: Can be used when other means of support are provided, such as saddles.

FLARED TROUGH END PLATE WITH FOOT: Used in the same situations as

mounts.

TUBE TROUGH END PLATE WITH FOOT: The integral foot eliminates the need for saddles at the end of tubular trough screw conveyors. Can be ordered with pedestal bearing mounts.

TUBE TROUGH END PLATE: Used when other means are provided for trough support. This end plate allows ease of maintenance when a the trough end. The end plate can be removed without providing temporary trough support.

TROUGH END PLATE WITH FOOT AND PEDESTAL BEARING MOUNT: The pedestal pillow block mount allows clearance for packing gland seals or when frequent seal maintenance is required. This is also useful for bearing isolation from damaging

styles.

COVERS

FLANGED COVER:-

FLAT OR SEMI-FLANGED COVER: Works well with spring clamps but supports

bolted in place properly so they are only recommended under special circumstances.

HIP-ROOF (RIDGED) COVER: Recommended for outdoor applications to help

Can be gasketed for additional protection.

FLARED TROUGH COVER (FLANGED):

SHROUD: U-troughs when a tubular trough is needed but

applications may call for the shroud to be continuously welded to a cover.

DAM:

with materials that tend to clump together.

GENERAL SAFETY

to install, maintain, and operate the conveyor components and assemblies manufactured and supplied by Conveyor Engineering

with the following:

MINIMUM PRECAUTIONS

assemblies and components must beinstalled with the following minimum conditions:

elements and the power transmission guards are in place. Prior to opening the conveyor for inspection, cleaning, or observation, the motor driving the conveyor shall be locked out electrically in such a manner that it cannot be restarted by anyone, however remote from the area. Only after the conveyor housing has been closed and all other guards are in place shall operation of the equipment commence.

2. discharge openings shall be connected to other

the conveyor must have an open housing as a condition of its use and application, the entire conveyor shall be guarded by a railing or fence.

1 2”

conveyor and warning signs shall be posted.

4. The conveyor shall have solid covers for areas not used for loading, feeding, or discharging.

covers, grating, or power transmission guards.

place hands, feet, any part of the body, or any article of clothing in the conveyor or opening.

8. Practice good housekeeping by removing any debris or unnecessary items found on or around the conveyor. Maintain adequate lighting around the conveyor.

SAFETY DEVICES CEMC can assist in the selection of electrical control devices that

The purchaser must select equipment and devices that conform to

and all local and national codes. Consideration should be given to one or all of the following devices and to others that may be appropriate.

speed and pull cord switches can be used to shut off

feeding conveyors whenever a receiving conveyor stops.

WARNING LABELSAll screw conveyors supplied by CEMC shall have one or more

When necessary, screw sections are typically removed starting with the end opposite the drive. Remove trough end, screw sections, coupling shafts, and hangers until damaged or worn section is removed. Reassemble conveyor in reverse order.

Periodically remove and inspect one of the drive shaft coupling bolts for damage or wear. Also inspect the coupling bolt hole. The drive shaft coupling bolts transmit more power than successive coupling bolts and will typically indicate the greatest wear. An accurate torque
