Bulk bag emptying system
This bulk bag emptying system unloads titanium dioxide (TiO2) and calcium carbonate (CaCO3) powder into 5 pound plastic bags. The titanium dioxide and calcium carbonate are additives in a rubber compounding system.
The additives arrive in 2,000 pound bulk bags. The bags are loaded into the emptying system. Below the station is a vibratory hopper that draws the material out of the bulk bag and into a surge hopper. Material is metered out of the surge hopper into the preformed plastic bag, which is secured on a bag clamp.
The bag clamp and plastic bags are on a digital platform scale. The scale controller starts and stops the flow of material into the plastic bag. The bag weight is plus or minus 2 oz. A control system manages the vibratory hopper, flow aid paddles in the surge hopper, and the filling of the plastic bags.
