Rotary Valve

Due to their constant speed, rotary valves feed and distribute the material evenly onto the screen cloth underneath. Due to the optimum distribution, the screen area is optimally utilized.

During feeding, the material to be conveyed is transported through the housing in rotor cells. To avoid wear, the design of the rotors is based on a low speed. In addition, the rotor lips are made of a flexible material to avoid crushing effects. Compared to chutes or other feeding devices, they require a lower overall height.
