The rotary mechanical fine screen is a fine screen that can be continuously and automatically removed. It is composed of many identical rake gear parts staggered and assembled into a set of closed rake gear chain, driven by a motor and reducer, through a set of sheaves and chains to form a continuous top-down cyclic movement to achieve The purpose of constantly removing the fine screen. When the rake tooth chain runs to the upper and back of the equipment, due to the guiding effect of the sprocket and the curved rail, the parallel rake tooth rows can be misaligned, so that the solid dirt falls into the slag trough by its own weight. The similar grid is easy to bring dirt into the channel behind the grid.www.khnwatertreatment.com
