An object is to provide a method for producing crumbs and powder rubber from used rubber products. Moreover, it aims at providing the apparatus which manufactures the crumb and powder rubber which have a predetermined particle size range. In accordance with the present invention, a method and apparatus for producing crumb / powder rubber is provided. The method and apparatus include a cooling step that is accomplished by a cooling means, wherein the rubber particles cooled at that temperature or at a low temperature and pretreated are controlled. The method and apparatus further comprise a grinding step achieved by the grinding means, the degree of grinding, i.e. the particle size range of the product, being controlled. |
