As material is conveyed, the rotation of the screws causes them to self-centre in the polymer conveyor tubes, eliminating or minimising contact with the tube wall, preserving material integrity. The rolling action of material also prevents the separation of blended products comprised of disparate sizes, shapes and bulk densities.
According to Flexicon, the screws are the only moving part contacting material, and are driven beyond the point at which material is discharged, eliminating wear and contamination related to product contacting seals and bearings.
The discharge housings of the conveyors are supported by dual booms cantilevered from the mobile base, allowing the discharge of material into processing equipment or storage vessels up to 12 ft above the plant floor. The hopper has a capacity of 20 ft3, and is designed with a steep back wall and diametrically opposed side walls skewed to form a trapezoidal area, the divergent angles causing non-free-flowing material to topple into the conveyor charging adapters.
