Crushing Rubber waste is mechanically crushed into smaller pieces before entering the reactor. Pulverizing In the pulverizing stage, roughly crushed rubber waste is converted into fine particles by high shear stress, and heated to the devulcanization reaction temperature quickly. Devulcanizing In the devulcanizing stage, fine particles of cross-linked rubber become greatly elongated by filling and shearing with the kneading disk, plasticized.    -- Deodorization     Because some characteristic odors arisen from reclaimed rubber can limit its practical application.       Deodorization is conducted by injecting high-pressure water into the barrel during devulcanization.

Cooling In the cooling stage, plasticized rubber then go through a cooling tank that drops the hot temperature resulted from devulcanization.  At the end of the cooling stage we have the reclaimed rubber.
