Flexible screw conveyor system with common hopper
Flexicon, Bethlehem, Pa., introduced the Twin BEV-CON Flexible Screw Conveyor system, featuring a common hopper and mobile base constructed and finished to sanitary standards.
Ready to plug-in and run, the self-contained system can fill two vessels with the same material simultaneously. Mounted on a frame with locking casters for in-plant mobility, it can be utilized in multiple locations and rolled to a washdown booth.
The hopper is equipped with dual discharge adapters, each of which charges a BEV-CON flexible screw engineered to move free- and non-free-flowing bulk materials that pack, cake, smear, fluidize, compress or are otherwise problematic to convey.
As material is conveyed, rotation of the screws causes them to self-center in the polymer conveyor tubes, eliminating or minimizing 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.
The screws are the only moving parts contacting material, and are driven beyond the point at which material is discharged, eliminating wear and contamination related to product contacting seals and bearings.
Discharge housings of the conveyors are supported by dual booms cantilevered from the mobile base, allowing discharge of material into processing equipment or storage vessels up to 12 feet above the plant floor.
The 20-cubic-foot hopper 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.
The unit is constructed of 316 stainless steel, and features sanitary quick-release clean-out caps, quick-disconnect discharge box access covers, washdown motors and a stainless NEMA 4X control panel with stainless conduit and liquid-tight compression fittings that permit washdown during changeovers and/or when conveying of corrosive materials. HMI controls allow manual and automatic start/stop and speed adjustment.
