It is suitable for operation in explosive environments.

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 on the silo outlet cone 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 OLI motovibrators fitted on the unit generate vibration of the Bin Activator every time the feeding device beneath the silo is started for feeding material. 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 discharge of powdery or granular materials from a silo or hopper. The use of this equipment ensures optimum feeding of the material according to a “mass flow” condition, thus avoiding bridging or rat holing phenomena.

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 from 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 were carried out to establish optimum body geometry. Agitator and feeder tool geometry and materials were tested, too, before choosing an optimal steel and SINT engineering polymer composite.
On request, MBF series Micro-Batch Feeders are supplied in food-grade versions with both FDA and EN- approval.

After less than half a turn material falls through the bottom outlet into an air stream passing through a pneumatic conveying pipeline connected with the bottom part of the Rotary Valve.
 

VL-type Slide Valves consist of a two-piece carbon or stainless steel frame partly coated with WAM’s SINT engineering polymer composite, as well as a sliding blade manufactured from SINT engineering polymer, carbon steel or stainless steel. The use of the unique SINT engineering polymer composites considerably increases resistance to abrasion as compared to traditional valves. Moreover, it avoids the use of flange gaskets.
VL Slide Valves are available in a variety of configurations including rectangular sizes. In the VLQ version the valves come with a square, in the VLC version with a circular open cross section, whereas in the VLR-version it is rectangular. The VLS version with square cross section has a pneumatic actuator integrated in its frame.

The body of the VM/VMM Pinch Valve is manufactured from aluminium alloy while the sleeves come in fabric-reinforced material. The sleeve support bushes are either made from aluminium alloy, hardened carbon steel, or 304/316 stainless steel. VM and VMM-type Pinch Valves are used for interception of material flow in pneumatic conveying systems, or other pipelines. In addition, they can be installed as a locking device for silo filling pipes.

Regarding VM only, by introducing compressed air through the threaded bore into the interior of the valve, the internal flexible sleeve is reshaped in such a way as to hermetically seal the passage. With VM Pinch Valves pneumatically conveyed powders, granules, fibres, dense mixtures and liquids can be equally handled.

Regarding VMM only, by introducing compressed air into the two single action air cylinders, the internal flexible sleeve is kept open. In case of no presence of air, the cylinders will reshape the sleeve in such a way that the passage is hermetically sealed. VMM Pinch Valves can equally handle pneumatically conveyed powders, granules, fibres, dense mixtures or liquids.

AD Diverter Valves consist of an aluminium die-cast casing and a swivel flap that closes one duct or the other. Internal sealing of the body is achieved through low friction gaskets.
Specific surface treatment is available to make the valves suitable for operation with different materials.

VAD-type Diverter Valves are suitable for use in pneumatic conveying lines for handling any type of material in powdery or granular form.
Through activation of the actuator direction of the material flow is changed. VAD-type Diverter Valves guarantee minimum pressure loss and contamination-free, pressure-proof operation.

VAR Diverter Valves consist of a cast aluminium casing and cover, an inlet and two outlets. The rotating internal drum optionally closes one of two outlets which are connected with pneumatic conveying ducts.
Rotation of the internal drum is activated by a pneumatic actuator.
Perfect sealing is guaranteed by internal, pneumatically inflatable seals. VAR Diverter Valves are suitable for diverting or converting any type of powdery or granular material.
Commutation of the tubular exit and diversion of the material flow from one duct to another is obtained by a pneumatic actuator which activates the rotating inner drum.

 

The VAB Flap Diverter Valve uses a swinging flap to divert material from one duct to another.
VAB Flap Diverter Valves are fitted on pneumatic conveying ducts in which switching the flow of material to different production lines is required. The VAB Two-Way Flap Type Diverter Valve is designed to meet the requirement of pneumatic conveying plants in re-routing powders, pellets or granules from one discharge point to another, with minimum pressure drop and high sealing efficiency.
 

DVA-type Diverter Flap Valves consist of a casing made up of two high-pressure die-cast semi-bodies manufactured from aluminium alloy, lined with SINT engineering polymer, and a SINT engineering polymer flap. The flap is either activated by a manual lever, a pneumatic or an electric actuator. DVA is a Diverter Flap Valve with one inlet and two outlets for the diversion of the flow of powdery or granular materials. Materials used enable quick cleaning and maintenance apart from offering great resistance to abrasion.

RBB-type FIBC Filling Stations consist of a steel frame and a bag filling unit including an inflatable seal that impedes dust leakage during filling. RBB-type FIBC Filling Stations enable efficient filling of bulk bags. The empty FIBC is attached to the four stretchers in the upper corners of the frame. Then the bag inlet is pulled over the loading spout of the station. Filling starts as soon as the seal around the bag inlet is inflated. Once the FIBC is filled up it is lifted by a forklift truck, removed from the steel frame and transferred to its further destination.

The DLP Lump Breaker consists of a square cross section casing with upper and lower flange, two horizontal rotating shafts equipped with chopping knives, a grid to hold back lumps, four end bearing assemblies with integrated adjustable shaft seal, an appropriately sized drive unit complete with power transmission. The DLP Lump Breaker is the ideal device for breaking up material lumps which have formed during handling or processing but are soft enough to be broken up.
Quick rotation of special chopping knives through a fixed grid does the job. The presence of two rotor shafts results in high throughput rates.

BELLOJET ZA Loading Bellows are used for efficient, dust-controlled loading of dry, dusty bulk solids into tankers. The spouts are provided with inner tapered cones to contain the flow of material and an outer double bellows to provide for dust removal. At the lower end of the Loading Bellows, a SINT engineering polymer-coated cone with special sealing properties is provided for connection to the tanker.

First the Loading Bellows is lowered from stand-by position towards the inlet spout of the tanker. As soon as the bellows outlet cone settles on the inlet spout of the tanker, the slack cable switch mounted outside the transmission box stops lowering of the bellows. The limit switch inside the transmission box stops both full extension and contraction of the bellows. Material loading is started by opening the silo outlet valve.
During filling of the tanker, the polymer coating of the outlet cone acts as a perfect dust seal. At the same time the filter fan continuously sucks dust through the external bellows into the integrated filter cartridges in the upper section of the unit exhausting excess air. A slack cable switch activates further extension of the bellows as the tanker lowers under the increasing material weight. A level monitoring device installed in the centre of the outlet cone signals maximum material level in the tanker compartment and orders immediate closing of the silo outlet valve. Contraction of the bellows back to stand-by position starts after a delay of approximately ten seconds in order to allow the filter to evacuate the remaining dust. Once the bellows is fully contracted, the cable limit switch inside the transmission box stops operation. The preset after shut-down cleaning cycle now provides for additional pulse-jet cleaning of the filter cartridges for another ten minutes.
 

WAH Continuous Horizontal Single Shaft Mixers consist of a cylindrical mixing drum vessel with an inlet at one end of the mixing drum, an outlet at the opposite end and a venting spout, a full material mixing shaft, two drum closing end plates that carry flanged end bearing assemblies complete with integrated air or gas-purged shaft seals, and a drive unit complete with power transmission.
Ploughshares or inclined blade-type shovels rotate as mixing tools in a special arrangement on the mixer shaft inside the drum vessel. The result is a turbulence in the mix that constantly involves all the product particles in the mixing process. The formation of dead spots or slow-movement zones in the mixing drum is prevented ensuring precise mixing. In some cases, to obtain the desired mixing effect, separately driven high-speed choppers can be installed.
