Bulk Bag Unloader for Manufacturer
BPS had the opportunity to build a bulk bag unloading station for the largest U.S. plastics
compounding manufacturer, based in Texas. The system shown is designed to discharge and convey calcium carbonate with a bulk density of 30 to 80 pounds per cubic foot at flow rates of 9,000 pounds per hour. Three custom manufactured components comprise this system including our Model BBU with vibratory agitation, a 20-cubic foot storage hopper, and a 12-foot long screw conveyor.
Due to the difficulty in conveying calcium carbonate, BPS doubled the motor horsepower and increased the shaft size on the screw conveyor to guarantee optimum performance. Also, the preliminary product testing dictated the incorporation of our more aggressive vibratory style unloader, rather than our normal paddle agitation design. (Shown to the left of the unloading station is our 2-Ton Hoist, Powered Trolley, Monorail, and Upper Bag Support Frame which mounts on top of the hopper and screw conveyor frame.)
