The horizontal pulper is used for grinding pulp. The structure of the horizontal pulper tank is designed so that stones and other impurities do not come into contact with the rotor and the pulper screen, thereby increasing its lifespan. Power transmission is achieved through a belt and pulley system. This device is employed for pulping LOCC, AOCC, etc., to separate plastics, polystyrene, and other light and heavy impurities from the pulper tank, preventing the transfer of waste and impurities to subsequent stages and their further fragmentation. This results in increased production capacity and a cleaner output.
