Vacuum ceramic filter is most suited to filter feed slurries with high solid concentrations (5-20% w/w) and particles ranging in size from 1–700 µm. The area of the filters available in the ceramic filter is up to 45 m, making them useful for metal and mineral concentrate processing. The ceramic discs are available in two types, cast plate and membrane plate. The cast plate is a one piece ceramic plate with a homogeneous surface and a granulated core. The filter medium of the cast plate is the thick walls, separated by ceramic granules. These features form a rigid mechanical structure. The membrane plate
