The size of the rubber particles is determined by the aperture of the granulating screen 82 and the rotating speed of the granulating motor 88, and according to the actual production requirements, the granulating screen 82 with a suitable aperture is installed to meet the granulation requirements of rubber particles with different sizes. In this way, the underwater granulation is adopted to reduce the granulation odor, and the outer surface of the rubber particles is rapidly cooled by the cutting water to ensure the granulation quality and cooling efficiency of the rubber material.
