Wam Shaftless Screw (Spiral) Conveyors
 
Wam SSC - Shaftless Spiral Conveyors
 
Description

The SSC Shaftless Screw or Spiral Conveyor is an alternative concept to the traditional shafted screw conveyor. Material is conveyed by an extra-heavy-duty shaftless screw that slides on a low-friction, wear-resistant liner inside the conveyor trough housing.

The U-section troughs, which are longitudinally divided, are manufactured in carbon steel or in 304 L / 316 L stainless steel, including an appropriate surface treatment. Fabricated parts except the screw, which is ultra-heavy-duty, are of the medium-heavy-duty type. The cross section of the lower part of the trough is slightly wider than the side channels to allow for the liner to be inserted in the lower trough part. After complete assembly of the trough the liner is kept in place by the upper trough side channels. At one trough end there is a vertical or flush-type outlet. At the drive end the screw conveyor is equipped with an end plate holding the end bearing assembly with flanged shaft coupling with the screw. The drive unit installed suits the application.

The SSC can be loaded from above into the open trough (standard), or through an inlet spout included in a bolted trough cover (option), or from the side through a special side inlet in the loading zone of the trough (option).
Function

The Shaftless Screw (spiral) offers a larger volume capacity and the possibility of handling particularly difficult materials such as those that tend to become tangled up or those that present highly variable particle size. Construction material properties, oversize thickness, as well as a special manufacturing process make the spiral highly resistant and extremely durable. Due to the absence of intermediate bearings, obstacle-free material handling is guaranteed. The completely enclosed trough prevents any material leakage. Trough covers with appropriate gaskets enable odour-free operation and form a barrier to any atmospheric agents to enter the system. At the same time the conveyor offers maximum access to the inside for inspection and cleaning. Maintenance is reduced to the minimum due to a small number of components. There is a vast choice of liners depending on the specific material characteristics.
SSC Shaftless Screw (Spiral) Conveyors Wam have been specially designed for handling of difficult heterogeneous materials like urban solid waste, screenings and floating matter, de-watered, thickened, conditioned sludge, packaged food, creams or pastes, waste from: meat, fish, fruit and vegetable processing. The main sectors of application are: wastewater treatment, sugarhouse rejects, fish industry, solid waste treatment, fruit and vegetable processing plants, beverage industry, pulp and paper, chemical industry, food industry in general, meat processing plants, abattoirs/slaughterhouses, restaurants, canteens, catering in general.

Wam Micro-screw Feeders
 
Wam MBF - Micro-Batch Feeders with Agitator
 
Description

The MBF Micro-Batch Feeder for continuous volumetric feeding of powdery or granular materials consists of a steel-reinforced SINT engineering polymer body (optionally body entirely manufactured in stainless steel), a horizontally mounted rotating agitator tool, a feeder screw beneath the agitator tool, a feeder pipe enclosing the protruding feeder screw, one drive unit each for agitator and feeder screw.

Tests on product flow and material stress have been carried out to establish optimum body geometry. Agitator and feeder tool geometry and materials have also been tested before choosing an optimal steel and engineering SINT polymer composite.

MBF series Micro-Batch Feeders are supplied in food-grade versions with FDA-approval on request.
 
Function

MBF series Micro-Batch Feeders for powder and granular product feeding are particularly suitable for poorly flowing materials which tend to clog, along with adhesive products.
Fed through a bag opening hopper, a bulk bag discharger, or another feeding device, the agitator tool manages to keep the material flowing reducing at the same time the possibility of formation of lumps or bridges.
The size of the product particles is of utmost importance when choosing the type of feeder screw. For example, fine, heavy materials call for tapered screws with reduced pitch flights, while granular, lighter materials require standard pitch cylindrical screws. Poorly flowing products with cohesion or bridging problems are homogeneously fed into the feeding zone by the blending shaft which is shaped according to the product properties.
Depending on the user's individual requirements, MBF Micro-Batch Feeders can be supplied with alternative feeder screws and blending tools and with various accessories.
MBF Micro-Batch Feeders have been successfully operating in the following industries: food, building, plastics, chemicals, packaging, environmental technology.
