Accommodate bulk material from multiple sources

| By Chemical Engineering



This company’s new flexible screw conveyor comes with a trough hopper (photo), and can receive material from multiple outlets of feeders, grinders, blenders and other process equipment. The hopper features an extended-length charging adapter that exposes 45 in. of the flexible screw rotating within an inclined U-shaped trough to charge material entering the hopper at any point. The rugged inner screw is the only moving part that contacts material, and is offered in numerous designs to handle both free- and non-free-flowing media. As it rotates, the flexible screw self-centers within the tube, providing ample clearance between the screw and tube wall to eliminate or minimize degradation. Material exits the conveyor below the drive point, precluding contact with bearings or seals. The hopper is equipped with a stainless-steel grate for worker safety, and to prevent oversized particles from entering the conveyor. — Flexicon Corp., Bethlehem, Pa.
