Hapman’s Helix Hi/Lo mobile flexible screw conveyor with integrated bag compactor and bag dump station/dust collection hood offers maximum dust containment. The all-in-one unit is specifically designed to ensure plant and worker safety when processing small bags of powders or bulk solids. Operators can easily add smaller bags of materials to a process using a bag dump station with dust collection hood. Filtration options down to 1 micron of efficiency are available to capture and confine material within the unit. The unit’s filters are cleaned using a reverse pulse-jet system to maintain filter efficiency. To further ensure material stays within the process, an integrated bag compactor allows the operator to dispose of bags through a pass-through port from the dump station. Dual pneumatic rams push a plate to compact a pile of empty bags down to an easy-to-manage 4 ft3 (.113 m3) bundle.
