Flexicon says its new flexible screw conveyor with trough hopper is designed to receive material from multiple outlets of feeders, grinders, blenders and other process equipment.
The trough hopper features an extended-length charging adapter that exposes 1143 mm of the flexible screw rotating within an inclined U-shaped trough to charge material entering the hopper at any point, Flexicon told ABHR.
The only moving part contacting material is the “rugged” inner screw, the company explained, and this part is offered in numerous designs to handle both free- and non-free-flowing materials, including products that pack, cake or smear, with no separation of blends.
“As it rotates, the flexible screw self-centres within the tube, providing ample clearance between the screw and tube wall to eliminate or minimise degradation,” the company explained.
“Material exits the conveyor below the drive point, precluding contact with bearings or seals.”
The hopper includes a stainless-steel grate for worker safety, and to prevent oversized materials from passing through.
“Smooth, crevice-free surfaces of the screw and tube interior allow in-place flushing with water, steam or cleaning solutions through a lower clean-out cap and/or upper discharge housing.
“The flexible screw can also be removed through the clean-out for separate sanitising and inspection of the polymer conveyor tube and stainless steel hopper, as well as the screw.”
