Filter presses utilize a special filtering medium to apply pressure to the material, allowing the liquid to渗析 out, making them a commonly used solid-liquid separation equipment. They were first applied in chemical industry production in the early 18th century and are still widely used in industries such as chemicals, metallurgy, dyeing, food, brewing, ceramics, and environmental protection. The filter plates are characterized by stable performance, easy operation, safety, and minimal effort. The metal squeezing cylinders are made from seamless steel pipes and are precision cast with plastic steel filter plates, featuring high-temperature and high-pressure resistance, and are durable.
