Vacuum ceramic filter is a new type of solid-liquid separation machine which is featured in energy-saving, high efficiency, low production cost, high automation level, smooth operation, low power consumption, low moisture of filter cake, low suspended solid and appears in the 1980s. It¡¯s extensively used for solid-liquid separation in such industries as ore beneficiation, metallurgy, petro-chemicals, paper making, coal, environmental protection and so on. Working principle: under the effects of pressure difference, as the slurry penetrates filter media, particles are blocked at the surface of filter media and filter cake is formed while liquid goes through the media and drained away so as to separate solid from liquid. Vacuum ceramic disc filters are the solid-liquid separation equipment, used to dewater mineral concentrates and Tba
