The alumina is mainly filtered by Kelly filter and vertical leaf filter(diastar filter). These filters generally work under high temperature and pressure, so the filter cloth requires anti-high pressure, anti-high temperature and high alkali resistance ability. Our cloth uses polypropylene monofilament yarns. The mesh is within 3-5um. It has excellent filtration effects and long service life. Currently cloth serves Indian alumina, Brazil alumina, China and Australia alumina companies. We have accumulated abundant experience in the alumina industry and get high praise from customers.
