Bulk Bag Piercing Hopper Bulk Bag Piercing Hopper has a removable triangular blade assembly, which pierces the center of unspouted bags allowing the material to discharge. The bottom of the bulk bag is fitted with a large diaphram, to reduce dust during the discharge process. The blade ruptures the membrane of the bags diaphragm causing the product to be discharged.
A wide variety of options are available to integrate bulk bag unloaders with material conveying systems and downstream process equipment. The material flow characteristics and the specifics of the customer’s bulk bag emptying application dictate the type of bulk bag discharger interface utilised.
Surge Hopper
Surge Hoppers with various capacity, can be utilised to provide continuous material supply while removing empty bags and loading full bags into the Bulk Bag Emptier. The inlet to the surge hoppers are typically connected to a bag spout interface option while the discharge is often connected to a conveying system.
Agitator Hopper
This U-shaped hopper has a mechanical agitator which eliminates the potential
of material bridging or forming a rat hole above the inlet to material conveying
equipment. The design of the agitatior draws the material away from the sides,
directing it through the center discharge on a consistent and reliable basis.
Combination Hopper
The combination hopper allows emptying of small bags, sacks, drums, and other containers in addition to bulk bags. Combination hoppers can be fitted integral dust collectors or tube stubs for connection to centralized dust collection systems.
Size Reduction Equipment
Rotating shaft(s) with staggered breaker bars deagglomerates materials as they pass through stators to reduce materials to a conveyable particle size.
