The granulation disc adopts the integral circular structure, and the granulation rate can reach more than 90%. The reducer and motor are driven by flexible belt, which can start smoothly, reduce the impact force and improve the service life of the equipment. The bottom of the granulation tray is strengthened by multiple radiant steel plates, which is durable and never deformed. The design of the thickened, heavier and stronger base does not need to be fixed with anchor bolts, and operates smoothly.
