Flexicon (Europe), Whitstable, UK, recently supplied two Bulk-Out® BFC-X bulk bag discharging systems with integral flexible screw conveyors to the Hoek plant of Styron Netherlands (previously Dow Benelux). One system unloads and conveys talc used to improve the mechanical properties of polypropylene compounds; the other unloads and transports an impact modifier in polycarbonate/ABS formulations. 

The equipment promotes complete evacuation of bulk bags and conveying of material to blending hoppers on compounding extruders. A programmable logic controller governs operation of the two dischargers and conveyors. Limit switches stop the conveyors from running when the hoppers under the dischargers become empty, and proximity sensors stop the conveyors when material has been transported to the compounding hoppers. The conveyors feature a flexible stainless steel screw of specialised geometry to handle non-free-flowing materials. www.flexicon.co.uk
