Vacuum Ceramic Filter is now proven the most energy-efficient and enviroment-friendly solid/liquid seperation device which produces an almost absolute vacuum resulting in very dry cake. It makes use of microporous ceramic plates through which no air will pass and only liquid could flow instead of filter cloth. The key to the ceramic filter is the porous ceramic filtration plate. The unique constructure of ceramic plate creates uniform micropores which establish the Capillary Action Effect creating an almost absolute vacuum ( less than 0.096Mpa) by which only liquid could flow through the plate and air canÆt pass through the plates. The ceramic filter has been widely used in the field of mining and metallurgy ( such as nonferrous metal mine and fine powder coal ), chemical processing, food, medicine and ceramics industry. The particle size of the slurry varies from 0.5¦m to 3mm, specially suitable for solid-liquid seperation of sand-character materials. The excellent de-watering function could also be gained for clay-character materials after adjusting the properties of slurry.
