Ceramic vacuum filter produced by our company is a kind of high-efficient and energy-saving liquid-solid separation equipment. Its design is advanced and its structure is reasonable. It is a high-tech product which integrates mechanical and electrical, microporous ceramic filter plate, ultrasonic cleaning, automatic control and other high-tech products. It uses porous ceramic filter plate as pass through. The filter medium can make the vacuum degree of the filtration process reach 0.096-0.097 MPa or more, so as to ensure its good dewatering effect. It can be widely used in metal mines, chemical industry, food, coal, medicine, environmental protection and other industries. The filter particle size is 0.2 um-3 mm, especially suitable for solid-liquid separation of sandy materials. For sticky materials, the slurry will be adjusted. The liquid property has good dehydration effect.
