Abstract: A separating device for separating materials from each other having different melting points, particularly a mixture of plasticized and non-plasticized solid material, includes a housing having a bore and a plurality of successively arranged disc within the bore. The discs are located relative to each other and are of such configuration as to define screening gaps. The plasticized material is separated by passage through the screening gaps as the mixture including substantially all of the solid material passes through the bore.

Abstract: A comminution device for the conversion of scraps of plastic into a free-flowing granulated material is provided without having to repeatedly feed the same scrap plastic into the device. The scraps of plastic are cut both longitudinally and transversely with the two types of cuts intersecting each other. Anti-clogging screens are not required.
