The large-scale brand plate-and-frame filter press is applicable to suspensions with high filter residue compressibility or nearly non-compressible properties. The suitable solid particle concentration of the suspension is generally below 10%, and the operating pressure is usually 0.3 to 1.6 megapascals. Special cases can reach 3 megapascals or higher. The filtration area can be adjusted according to the number of plates and frames used. The plates and frames are usually square, with the inner side length of the filter box ranging from 200 to 2000 millimeters, and the frame thickness ranging from 16 to 80 millimeters. The filtration area is 1 to 1200 square meters. The plates and frames are compressed manually by screws, electrically by screws, or hydraulically. The plates and frames are made of materials such as wood, cast iron, cast steel, stainless steel, polypropylene, and rubber. Applications: Chemicals, dyes, petroleum, ceramics, pharmaceuticals, sugar, starch, paint, metallurgy, and wastewater treatment, etc.
