Customer needed a solution for conveying EPDM (ethylene-propylene-diene monomer) rubber particles. KWS worked closely with Lion Copolymer to design a unique conveyor for the application. EPDM rubber is fed into the conveyor by a perforated dryer belt that travels across the top of the twin screw conveyor. Excess EPDM falls through the perforations where they get picked up by the twin screw conveyor and discharged into a collection bin. EPDM rubber is used in a wide variety of outdoor and automotive applications due to the resistance to oxygen, ozone, heat and weathering.
