This automated bulk bag unloader system uses a fully integrated, 4-stage material conditioning sequence to prepare an extremely 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. Next, dual hydraulic massage paddles, each with 2,200 pounds of paddle pressure, further reduce material to chunk sizes. A bag spout valve, with 1,000 pounds of material break-up force, and capable of breaking up a static column of material, then reduces the material for supply to the final stage where a high-capacity, size reduction crumbler breaks material into ¼-inch pieces for conveying downstream.
