Chain Plate Rotary Rake Bar Screen

Chain Plate Rotary Screen Rake

Overview and Application  
    The LF type chain plate rotary screen rake is a continuous-operation cleaning device produced by our company. It intercepts debris in liquids using grid bars. The rake plates descend behind the grid bars to the bottom, then rotate to the front of the grid bars, lifting the screened residue upward to the discharge port for removal, achieving solid-liquid separation. The width can reach up to 4 meters. The rake plates are driven by plate chains on both sides, operating in a cyclic motion. The spacing between rake plates is 1.2m to 1.5m, effectively raking larger debris such as wood blocks and bamboo poles, as well as sand and mud at the bottom of the screen.
    Widely used in various rainwater and sewage pumping stations in urban sewage treatment, water supply lifting pumping stations, and at the inlets of sewage treatment plants to intercept and remove floating debris. It is an ideal decontamination machinery.

Performance Features
