Emboxable version, an efficient transport method



ZEPPELIN

STORAGE SILO

UtilizationFor several (at least two) silos of equal or similar size.

System descriptionZEPPELIN emboxable silos are manufactured with minor differences in diameter (difference 50-100 mm) and are equipped with a flange connection at the transition between the cylinder and the hopper respectively roof. This method allows to embox the cylinders, hoppers, and skirts of a silo group into each other for transportation. In case of increased requirements for dust density and gas density we recommend a density welding at the flange connection after installation on site.

AccessoriesAccessories which protrude more than 25 or 50 mm from the silo wall and which shall be fitted to the silo cylinder are delivered in screwed execution for installation on site. This method can only be realized thanks to the exact manufacture of ZEPPELIN emboxable silos in vertical position.

CalculationThe silo size is stipulated based on the minimum volume of the smallest silo or on the average volume of the silo group. The number of ZEPPELIN emboxable silos per transport package depends on the max. permissible package weights.

TransportFor transport of the packages are put on wooden saddles or wooden supports depending on the requirements. For overseas transport the open front surface at the cylinder is sealed with wooden covers. The accessories are stowed inside the packages during transport. For transport the hopper cones will be fixed to the flange of the cylindrical silo shell or stowed in the dead space inside the skirt (depending on the length and weight of the packages).

AssemblyOn site the emboxable silo parts (skirts respectively hoppers with short skirts and silo cylinders) are deboxed. The skirts are lifted onto the foundation base rings. The flange connections are bolted together. For the silo erection normally one crane is required. An additional fork-lift truck will be required to dismount the components of a package.

AdvantagesConsiderable reduction of the total volume required for transportation over far distances respectively overseas (e.g. for the transport of two emboxable silos approx. 45% of the normally required shipping volume can be saved, for the transport of six silos approx. 80% can be saved) whereas the optical quality of the silos is not deteriorated. Quick and easy erection of the silos (the erection will take approx. 4 h per silo if it is carried out by 3 skilled workers).

BLENDING SILOS

Zeppelin Centro–Blend

ZEPPELIN

BLENDING SILO

Centro-BlenderContinuous and batch-wise blending and homogenizing of bulksolids

UtilizationFor solids having easy to poor flowability (plastic powders, recyclingmaterials, pellets, flowable elastomers)

Components- Vertical central blending pipe with intake openings at different

levels- Cylindrical blending chamber

System descriptionVia the intake openings solids are simultaneously withdrawn froma multitude of layers from the annular space at different layersand led into the central blending pipe. The number and size of theintake openings are determined under consideration of the blendergeometry and flow properties of the bulk solids.

Advantages

The Zeppelin Centro Blender offers the following advantages:

- No negative influence on the blending process- Consequent design for mass flow- Easy cleaning in case of change to a different product- Easy integration in the production process as the blender can

be used for continuous and batch-wise blending- High blending efficiency due to simultaneous withdrawal of

solids from different layers- For many applications of homogenization a single pass is

sufficient, especially when the blender content is composed of a high number of individual batches

Zeppelin Multi–Pipe Grafity Blender

ZEPPELIN

BLENDING SILO

Multi-Pipe Gravity Blender

For free flowing, dry and cohesionless bulk solids with particle sizes above approx. 0.5 mm, especially pellets.

DesignWith extruded three-compartment pipes made from aluminium respectively stainless steel.

Each individual chamber of the blending pipe has several intake openings.

DescriptionVia the intake openings of the blending pipes the bulk solids will flow from different zones in the silo into the central hopper outlet, resulting in different residence times which are used for blending.

With continuous operation solids are fed constantly or in regular intervals into the blender while the respective quantity is withdrawnvia the blending pipes and the hopper outlet. Thus, the filling levelremains almost constant.

With discontinuous operation the blender is filled successively withdifferent batches. After filling the material within the blender is recirculated or discharged directly. As during discharge the filling level is reduced constantly, solids are withdrawn successively via intake openings at different heights of the individual blending pipe compartments.

Only at the start of the homogenization process a quantity of approx. 15% of the blender content has to be recirculated as mainly bulk solids with the same composition can be found in the discharge cone, the blending chamber and in the lower area of the blending pipes.

AdvantagesZeppelin Multi-Pipe Gravity Blenders are applicable for different filling levels up to approx. 25%. Design of the hopper for mass flow guarantees good homogenization results.Zeppelin Multi-Pipe Gravity Blenders can be used either continuously or for batch-wise blending.For many applications the homogenizing effect of one single pass issatisfactory due to the high number of discharge points. Thus, therecirculation via an external pneumatic conveying system will, therefore, only be necessary for a very high degree of homogeneity or extremely wide fluctuations of product quality.

Zeppelin Multi–Flow Blender



ZEPPELIN

BLENDING SILO

For homogenizing batches or production-related variations of pellets and powders. Easy to retrofit to existing storage silos.

DescriptionThe blending effect of the ZEPPELIN Multi-Flow Blender is achieved by the installation of a blending hopper resulting in different flow velocities and, thus, in different residence times of the bulk solids. Multi-Flow Blending Silos are most advantageous if the ratio of their height to the diameter is less than 2,5.

Design- Multi-Flow Blending Hoppers can be welded into silos during

fabrication. Optionally existing silos can be retrofitted with the hopper. For retrofitting the hopper can be subsequently welded or flange-mounted to the silo.

- The Multi-Flow Blending Hopper is designed for mass flow ensuring an optimum blending result and complete discharge of the silo.

- For support of the hopper plane vertical ribs are used which facilitates cleaning of the silo.

OperationThe Multi-Flow Blender is suitable for continuous operation as well as for discontinuous, batch-wise operation. The blending process can optionally be improved by external recirculation.

In most cases for homogenization of batches one single pass is sufficient. If the ratio of the silo height to the silo diameter is very small and if only a few batches shall be homogenized recirculation should be foreseen.

AdvantagesThe ZEPPELIN Multi-Flow Blending Hopper offers you the followingadvantages:

- Easy and quick method to retrofit existing silos- Good blending results due to a wide residence time distribution

and due to mass flow - Easy cleaning due to no additional internal installations in the

blending hopper- Favorable solution for blending of bulk solids

Vibrating bottom

ZEPPELIN

The vibrating bottom serves to discharge bulk solids, which are not free-flowing. The vibrating bottom is attached at several points and suspended below the silo cone, so that one or more unbalance engine(s) can set him to vibrate. The vibrations are transferred to the product in the silo cone and enable the bulk solid to be discharged. The engine speed of the unbalanced engine is already pre-set when delivered and has to be adjusted only in exceptional cases. The transition of the silo cone to the vibrating bottom is perfectly sealed by means of an extruded special gasket, which is clamped between flanges.Equipment:Main gasket in U form with two clamp flanges Discharge gasket to the subsequently connected device fixing device.

Assembly

ZEPPELIN

AssemblyWe will carry out the complete assembly of silos or provide the services of supervisors or skilled assemblers on request. As a rule, the assembly operation breaks down into the following stages:

1. Offloading of the silo and accessories from the wagon or transport vehicle with a mobile crane.

2. Transfer from the offloading siding to the construction site with a crane or low-loader.

3. Screw-mounting of the ladder and filling pipe to the appropriate silo.

4. Levelling up the foundation base rings.5. Setting the silos upright and placing them on their base

rings6. Screw-assembling the silos, positioning and mountingthe

railings and connecting walkways.

If only a small number of silos are involved, it is advisable for the crane and vehicles to be provided by the customer, since he will be familiar with local conditions. We will, however, provide all the advice at our disposal. Experiences crane operating companies are usually able to provide suitable equipment when notified of the operation concerned. Alternatively, they can consult Zeppelin for advice.Given efficient organization, and provided the silos are erected on foundation base rings and need only be transported over reasonably short, convenient distances, two assemblers can erect up to six silos on one day and complete the assembly on the second day (32-40 working hours). If the customer can supply fitters form his staff(who must not suffer from vertigo) it should be sufficient ifwe supply a supervisor to direct the customer’s personnel(one to two people).We calculate the costs of assembly as follows:- Travel and standard working time, at home or abroadSupervisorSkilled assemblerOvertime supplements 25 %, 50 % or 100% of theabove rates, in accordance with the tariffs agreed by theSuedwuerttemberg Hohenzollern Metal Industries.- Travel allowance in accordance with the applicable tariffagreement. In the case of outward or return travel bypersonnel at an intermediate time of day, the travelallowance is reduces in accordance with the recognizedregulations.
