National Bulk Equipment Inc. says the automated bulk bag unloader system uses a four-stage material conditioning sequence to prepare an agglomerated, rock-like material for supply to a downstream liquification process. The dual, opposing bag hoist design enables high-volume input of material to the first conditioning stage where two, hydraulic de-blocking rams each deliver 28,000 pounds of direct material force, according to NBE. Dual hydraulic massage paddles each have 2,200 pounds of paddle pressure.
