Fixed or wheel-mounted discharge hoppers are built in AISI 304 or 316 stainless steel with appropriate surface finishing treatment.
Storage hoppers come in sizes from 100 lt to 1,000 lt, with geometrical design and can be equipped with hoods for collection to the customer’s particulate exhaust system.
On request, the hoods are supplied complete with suction and filtration system to trap particulate generated during bag emptying, and with cleaning of the filtering sleeves or cartridges by compressed air.
The bag dump stations are designed for connection to the GIMAT mechanical or pneumatic powder conveyor system.
This system is designed to be able to introduce accessories for easing the fluency of the materials contained inside and control their level automatically.
Among the former we find:
- Mechanical bridge breakers in various versions.
- Eccentric mass vibrators
- Vibrators or jack hammers
- Bin activators
Automatic level controls:
- Level indicators having a rotary blade;
- Capacitive sensors;
- Diaphragm level indicators and other more specific types.
In addition to the mechanical bag breakers in the standard version, there are numerous versions of special bag breaker hoppers that GIMAT designs and builds to order to satisfy the specific need.
Special storage hoppers
Among the bag cutting hoppers with suction hoods there is one designed for hazardous, toxic or high particulate products that calls for the use of a glove box – a sealed cab reached with gloves.
The operator inserts the intact bag through the opening of the side door with gas springs that is then closed. After that, the operator accesses the inside of the bag cutter cab using the gloves and the cutting kit to open and pour the contents of the bag inside, with the suction filter on to prevent clouds of particulate. After the confined environment has been dedusted, a new bag can be inserted. The empty bag is expelled either laterally (from the side opposite the intake) collecting the bags inside a special flexible container, or through the filling hatch. The exhaust air filtered by the centrifuge fan will, when necessary, be conveyed outward and sent through an absolute HEPA filter.
