Hapman introduces its Helix Hi/Lo mobile flexible screw conveyor with integrated bag compactor and bag dump station/dust-collection hood to offer 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 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 a 4-foot 3-inch (.113 m3) bundle.
The Helix Hi/Lo conveyor is designed to allow a single worker to safely and easily handle washdowns, auger changeouts and servicing from floor level. An electric actuator automatically lowers the auger to accessible heights. Optional external vibration can be added to assist with material flow.
Stainless steel is utilized for construction with sanitary or food grade finishes available. The unit can convey to heights up to 12 feet (3.65 m) and at rates up to 25 cfm (0.7 cmm).
