Chamber filter press takes filter cloth as the medium to separate solid and liquid. It is a separating machine with wide rang of particle size. The filter cloth spreads in a filter board surface, it is supported by the swelling groove of filter board, when the filter board is clamped, filter cloth turns to seal materials, and the cavity between every two filter board forms a separated filter room. During the filter processing, the materials come through the central opening into filter room, the filtrate flow by the feeding pressure, flow out of the filter board after converged. Chamber filter press can be divided into two types according to filtrate discharging ways: open channel flow and under channel flow.
Plate and frame press filter separate the solid from the liquid in filter form. It is a separating machine with wide rang of particle size. Materials come through the filter room that made up of filter board and filter frame. Under the pressure of feeding materials, the filtrate flow through the medium that made up of filter board and filter frame-fiber gap of the filter cloth, arriving at the pattern surface, flow out of the filter board after converged. The solid left in the filter frame forms filter cake. Plate and frame filter can be divided into two types according to filtrate discharging ways: open channel flow and under channel flow.
