Top 10 Rotary Vacuum Disc Filter Factory in the world 2025 - Blog

Introduction to Rotary Vacuum Disc Filter

A rotary vacuum disc filter is a type of continuous - operating filtration device widely used in various industries such as mining, chemical, food, and environmental protection. It consists of a series of circular discs mounted on a horizontal shaft and submerged in a slurry tank. A vacuum is applied to the interior of the discs, causing the liquid in the slurry to be drawn through the filter media on the disc surface, while the solid particles are retained as a filter cake. As the discs rotate, the filter cake is continuously formed, washed (if required), and finally discharged. This type of filter offers high filtration efficiency, large processing capacity, and the ability to handle a wide range of particle sizes and slurry characteristics.
