The plate and frame filter press is a relatively new type of high-efficiency and fast filter. The motor type adopts hydraulic execution and PLC control mode, which improves the reliability, stability and safety of equipment control. The filter area of the plate and frame filter press is several times larger than that of the general filter, and it is widely used in the field of filtration and separation of suspensions. The plate and frame filter press has simple structure, compact equipment, large filtering area and small floor space, high operating pressure, low water content of the filter cake, strong applicability to various materials, and is suitable for intermittent operation.
