Bulk Bag Discharge System

The SacMaster bulk bag discharge system has a modular design that provides flexible positioning to meet many process requirements. The agitation system allows the SacMaster to empty even the most difficult bulk solids from bulk bags of all types and sizes. Free-flowing plastic granules to poorly flowing titanium dioxide or calcium carbonate fall in the range of materials handled effectively.

When the bag is full of material, dual-pivot paddles push against the bottom of the bag to break material bridged over the outlet as well as agitate the sides of the bag near the spout, stimulating material movement. As the bag empties, air cylinders push the paddles further toward the center of the bag until a proximity sensor located on one of the air cylinders determines that the bag is near empty. The proximity sensor holds the air cylinders in the extended position to empty the bag corners while continuing to pulse the bottom of the bag. This facilitates a smooth flow of material from the bag, eliminating waste and improving process efficiency.

Advantages which pay off

Partially emptied bulk bags can remain in the discharge station until further processing is required. An optional iris valve closes the receptacle until processing has resumed. Dust containment units are available for controlling dust and volumetric or gravimetric feeders can be integrated into the system as well.
