Working Principle

1. Under the pressure of the feed pump, the material and liquid to be filtered shall be sent to each filtration chamber, and the solid and liquid shall be separated through the filtration medium (appropriate press cloth shall be selected according to different industries).Pile up on the cloth to form a filter cake.The filtrate passes through the filter cloth and flows along the groove of the filter plate to the outlet hole channel below to discharge centrally.
2. After filtration, the filter residue can be washed with clean washing water.After washing, compressed air is sometimes injected to remove the remaining washing liquid.
