About
The Disc Vacuum Filter is a solid-liquid separation equipment that uses vacuum as the driving force for slurry separation. The machine incorporates advanced technologies such as filter disc guide frames, variable-speed stirring, reverse-blowing unloading, and automatic centralized lubrication, making it a high-performance and reliable dewatering device. This is a new type of disc vacuum filter specifically designed for iron concentrate and non-ferrous metal concentrate dewatering, and is also suitable for use in coal washing and beneficiation, non-metallic mineral processing, chemical industry, and environmental protection.

Working Principle
The Disc Vacuum Filter is composed of individual circular discs, each featuring a sector-shaped blade that serves as a separate filtration unit. A fabric sleeve is wrapped around the sector blade to create a filter chamber. The filter discs are driven by an electric motor via a reducer and open gears, rotating clockwise. The slurry in the filter chamber, with the help of a vacuum pump and the pressure difference formed on both sides of the filtering medium, adheres to the filter disc to form a filter cake. A stirrer rotates to prevent solid settlement. Once the filter cake rises above the liquid level, it continues to remove moisture under vacuum. The filtrate passes through the filter fabric, through the filtrate pipes, and is discharged from the distribution head. The filter cake is discharged into the discharge trough in the unloading zone by reverse blowing, and the entire process operates in a continuous cycle.

Work Conditions
The particle size of the solid in the slurry ranges from -100 mesh to -400 mesh.
Slurry temperature ranges from 10℃ to 50℃, non-corrosive.
(3) Suitable for pulp concentrations ranging from 35% to 65% (for metallic minerals) or 20% to 40% (for coal or other light materials).
