Bulk Bag Unloader Handles Caustic Material with Enclosed, 4-stage Process

October 6, 2010

The bulk bag unloader system, handling highly caustic, severely agglomerated material, operates as a closed process; ensuring the protection of operators from migrant, airborne material and eliminating the possibility for contamination of material in-process, according to the manufacturer. The highly compressible material requires integrated bulk bag conditioning to provide sufficient material supply. A sequential, 4-stage process, including: hydraulic de-blocking rams each with 28,000 pounds of force; hydraulic massage paddles each with 2,200 pounds of paddle pressure; a patented enclosed, bag spout interface to collect dust and aid discharge; and automatic bulk bag loop retractors to ensure complete material discharge, work together to condition the material from football-sized chunks to ¼-inch, or smaller particles. The enclosed system conveys the material downstream at a rate of 18,000 pounds per hour.
