 At times flowability of certain powders is so poor that discharge from silos assisted by flow aids like aeration pads, pneumatic hammers, hammer blasts or even air cannons is impossible.
In such cases a Bin Activator is the ultimate flow aid and extracting device for such materials.
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.
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.
| Model ZA Tanker Loading Bellows with Integrated Dust Collector |
Certain bulk materials cannot be stored in cylindrical silos with a tapered outlet cone because no flow aid would be sufficient to extract them. As a result, mechanical extracting and feeding devices must be adapted to the cross section of the outlet. WAMGROUP offers a variety of equipment for discharging bulk materials including bin activators and loading bellows.
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 bellow to provide for dust removal. At the lower end of the Loading Bellow, a polymer-coated SINT® cone with special sealing properties is provided for connection to the tanker.
The BELLOJET® dust filtration system, that includes eight cartridges to provide an overall surface area of 10m2 (108 sq ft), is equipped with a 2.2 kW (3.0 HP) fan.
BELLOJET® ZA Telescopic Loading Bellows are suitable for continuous loading at a maximum flow rate of 250m3/h (147 cfm) of bulk material.
The outlet can be equipped with an anti-spillage device which acts as a dustproof stopper as the Loading Bellow is being raised. The equipment features an electric winch.
The fan of the BELLOJET® dust filtration system increases the efficiency of the filtering elements. Due to an after-shutdown-cleaning-cycle, the filter elements are always in perfect condition at the start of each new loading.
| Model ZC Open Truck Loading Bellows With Integrated Dust Collector |
 BELLOJET® ZC Loading Bellows are used for efficient dust controlled discharging of dry, dusty bulk solids into open lorries / trucks. The spouts are provided with inner tapered cones to contain the flow of material and an outer double bellow to provide for dust removal.
BELLOJET® ZC Telescopic Loading Bellows are suitable for continuous loading with a maximum flow rate of 250m3/h (147 cfm) of bulk material. At the lower end of the Loading Bellow, a special dust skirt seal is provided for settling on the truck skip or stockpile. The Loading Bellow is operated by an electric winch.
