Flexible Screw Conveyors for Mining Applications

Flexicon's High Capacity Flexible Screw Conveyors for mining applications transport filter concentrate/cake, aggregates, abrasive minerals and dry additives such as ammoniuim nitrate, lime and thiourea, dust-free. In addition to free-flowing materials, it can convey non-free-flowing materials that tend to pack, cake, smear or seize, with no separation of blended products.

The enclosed stainless steel (shown) or carbon steel conveyor tube, which is offered in a wide range of diameters to suit low- to high-capacity applications, can be routed horizontally, vertically or at any angle, through small holes in walls or ceilings.

The rugged inner screw is the only moving part contacting material, resulting in reduced maintenance and increased reliability. The screw is driven above the point at which material exits the conveyor, preventing material contact with seals.

A removable end cap at the lower end of the conveyor allows reversing of the screw for evacuation of material, in-place flushing of the crevice-free interior, and quick removal of the screw for cleaning — with minimal labor or downtime.

The conveyor is offered in stationary and mobile models constructed of carbon steel or stainless steel.
