The granulation tray is equipped with three outlets, which is convenient for intermittent production operations. Besides, the reducer and motor are driven by flexible belts to reduce the impact force and improve the service life of the equipment. The bottom of the granulation tray is reinforced with multiple radiant steel plates, which is durable. Thus, heavy, thickened, and solid base makes machines operate stably. The main gear of the granulator adopts high-frequency quenching, and the service life doubles in this way. The granulated face plate is lined with high-strength glass fiber reinforced plastics, which are anti-corrosion and durable.
