Filter belt of polyester or dacron mesh is designed as screen media for high pressure press-filters and belt presses filtration system. The synthetic filter cloth has great strength, stability, excellent chemical resistance and cake release properties. The fabric is woven with spiral wire in big loop or large loop, medium loop, and small loop to achieve varified filtration ratings. The mesh belt is popularly used used for paper making, as drainage filter mesh for pulp machine pressing uses, also coal washer, metal and mineral concertration and food industry. We offer press filter screen with seam, non woven and coated mesh types.
