The specialized filter press for coal washing is an important equipment for coal preparation plants to achieve in - plant recovery of coal slime and closed - loop circulation of washing water. With the continuous promotion of mechanized coal mining technology in China and the rapid development of coal preparation technology, coal preparation plants are getting larger, and situations such as deteriorated coal quality and increased coal slime occur. Therefore, higher requirements are put forward for the equipment of the coal slime water treatment system, which in turn promotes the continuous improvement and update of filter presses, and a number of new high - efficiency specialized filter presses for coal slime emerge. This filter press adopts a combination of open and closed flow discharge methods in its design, which improves the filtration speed. Based on the level gauge, it can adapt to coal slime water of different concentrations. Controlled by PLC, it can automatically complete the processes of feeding, filtration, and unloading, reducing the labor intensity of workers. Moreover, the moisture content of the filter cake can be adjusted within a certain range as required. The specialized filter press for coal washing is characterized by high technological content, fully automatic operation, safe and reliable equipment, strong adaptability to rapid and efficient filtration of materials, low moisture content of the filter cake, high production capacity, and good economic results. The specialized filter press for coal washing is mainly used for dewatering clean coal, tail coal, and raw coal slime, and has high application value. Therefore, the coal slime filter press will become the first choice for specialized filter presses in coal washing plants.
