Screening problems result from particle-to-particle bonding (agglomeration) and by particles clinging to the screen mesh, both caused by excess static build-up, which also increases the risk of arcing, which can cause dust ignition in extreme circumstances. By grounding a separator’s screens these issues can be minimised.
SWECO has already produced conductive elastomeric gaskets capable of grounding the screens to minimise static build-up, but the C2 is also made from FDA approved components. The patented SWECO C2 Gasket is 24 inches by 72 inches round and is a co-extruded product of FDA white silicone and conductive black silicone, and thus can be used in food processes. The FDA white silicone element is the only portion exposed to product contact, while the black conductive component of the gasket makes contact with the frames and the outer lip of the screen tension ring (for SWECO STP and spot-welded screens only).
