Principle of composite woven bag separator: During operation, the drive shaft drives the chassis and grinding rotor to rotate strongly, and the pulp moves from top to bottom along the rotor surface. Then, it is thrown from the lower part of the rotor towards the groove wall and subjected to the high-strength eddy current kneading cycle generated by the strong motion of the cutter head. This causes various paper and plastic materials to flip up and down inside the machine, rotate in the circumferential direction, and be constantly impacted with high strength in all directions. With the flying blade of the cutter head cutting and continuous friction between the sieve plate, the pulp is fully dispersed into fibers and moistened to avoid cutting or damaging the fibers, and flows out from the pulp outlet under the sieve plate. Plastic sheets, adhesive backing sheets, plastic films, and other impurities are crushed less (without forming debris) and discharged from the slag outlet next to the tank, completely separating the film and fibers.
