A brief discussion on the material and types of filter plates of plate and frame filter presses
Composition of filter press The filter press is mainly composed of main frame, filter plate , filter cloth, water nozzle, electric control cabinet, hydraulic station and other components. The filter plate is a component used in the filtration process, and its function is to form the filter medium. Filter plates are usually made of materials such as polypropylene or polyethylene and are square, rectangular, or round in shape. They are acid-resistant, alkali-resistant, high-temperature resistant, and wear-resistant. During the filtration process, the filter plates are placed on both sides of the filter press. The liquid or suspension flows in from the feed hole of the filter plate, and the solid particles are trapped on the filter cloth, thereby achieving the filtration effect. At the same time, the number and size of filter plates also directly determine the filtration area and filtration capacity of the filter press. A piece of filter plate forms a tightly close...
