Floor Plan

Since in 1969, Vainer Marchesini, founder, current chairman and C.E.O. of WAMGROUP® manufactured his first screw conveyor, the WAM® brand has come to stand for innovation in Bulk Material HandIing Technology and Equipment Supply. The start was made with the development of standard cement screw conveyors for the concrete industry. Later the product range was extended to filtersystems, bucket elevators, silo equipment, valves, loading bellows, mixers, products for waste water treatment etc. and other industries such as asphalt, cement milling, lime and plaster processing, biological sludge, animal feed, flour mills, chemicals, foods and glass.

The company is based in Modena, Italy and employs people at more than 60 locations in 40 countries. The German subsidiary WAM GmbH is accounting for the German speaking countries Germany and Austria.

BA Bin Activators

The BA Bin Activator is a device of tapered conical shape that due to vibration facilitates material flow from hoppers or silos. It consists of a seamless carbon or stainless steel cone manufactured on a sheet metal lathe, a seamless SINT® engineering polymer seal with integrated upper and lower flange, suspensions for connection of the Bin Activator with the silo, as well as one or two electric vibrators.

Function

To fit the BA Bin Activator, the silo cone has to be shorter than usual, leaving a wide outlet section. A flange supplied before or together with the Bin Activator is welded to the silo outlet on site. Special suspensions and a seamless flanged SINT® engineering polymer seal form a flexible connection between silo and Bin Activator. One or two electric vibrators fitted to the unit generate vibration of the Bin Activator every time the feeding device beneath the silo is started for material extraction. During operation the Bin Activator describes a gyratory movement which is transmitted to the material inside the silo. The result is smooth material flow through the Bin Activator outlet into the connected feeder.
BA Bin Activators are used in various industrial applications to facilitate discharging of powdery or granular materials from silos or hoppers. The use of this equipment ensures optimum feeding of the material and causing ¿mass flow¿ inside the silo and avoiding bridging or rat holing phenomena.

MBF Micro-Batch Feeders with Agitator

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.

TX Stainless Steel Tubular Screw Conveyors

The modular TX Tubular Screw Conveyor system is highly versatile. TX Screw Conveyors are manufactured in stainless steel with a suitable surface finishing grade appropriate for the application. Manufacture of the fabricated components is carried out on machines that guarantee a perfectly smooth surface due to which material residue is reduced to the minimum. TX Tubular Screw Conveyors are made up from a tubular trough that is equipped with at least one inlet and outlet spout, an end plate at each tube end, helicoid screw flighting welded on a centre pipe with a coupling bush at each end, two end bearing assemblies complete with adjustable shaft sealing unit, and a number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, TX Tubular Screw Conveyors are equipped with a gear motor that is suitable for the application. Depending on the material to be handled TX Tubular Screw Conveyors come in a light or medium-heavy-duty design.

TX Screw Conveyors are available with ATEX, zone 22 certification.

Function

The TX Tubular Screw Conveyor system offers a variety of solutions for conveying or feeding powdery or granular materials. TX Tubular Screw Conveyors are suitable for applications in which any contamination of the material handled has to be strictly avoided and in which absolute cleanliness and perfect resistance to corrosion is required.

In particular, TX Tubular Screw Conveyors are used in environmental technology, in flour and animal feed milling, in food processing and packaging, in plastics and chemicals, as well as in the pharmaceutical industry.
