Hapman has introduced the 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 easily add smaller bags of materials to a process using a bag dump station with dust collection hood.

Filtration options down to 1micron 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 4ft 3in (.113m3) bundle.

Steve Grant, bag dump station and bag compactor product manager at Hapman, said: ‘Dust containment is a real issue for today’s processors.

‘For example, the chemical industry is concerned because material in dust form can threaten plant and worker safety.

‘And it is a concern for food processors because ingredients on the plant floor invite pests and can pose a safety threat to the plant and workers,’ he added.

The Helix Hi/Lo conveyor’s design allows a single worker to safely and easily handle wash-downs, auger change-outs and servicing from floor level.

An electric actuator automatically lowers the auger to an easy-to-access height.

Exclusive T-handle couplings allow disassembly in minutes, according to Hapman.

Optional external vibration can be added to assist with material flow.

Stainless steel is utilised for construction, with sanitary or food-grade finishes available.

The unit can convey to heights of up to 12ft (3.65m) and at rates up to 25cfm (0.7cmm).
