DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separating and crushing apparatus for shearing a tire piece and separating a wire contained in the tire piece from a rubber portion when crushing a discarded tire.

2. Description of the Related Art Conventionally, when processing a recycled product for reuse, the waste tire is cut into several pieces of tire as a pretreatment step and then finely crushed by a crushing device. For example, as shown in FIG. 30, the crushing blades C1 and C2 of the crushing device generally convert the waste tire piece T1 into the crushed piece T1.
a, and cut into T1b. The wire W such as a belt wire included in the waste tire piece T1 is cut at the same time when the rubber portion is cut. The wire W remains in the crushed pieces T1a and T1b. In this way, the crushed pieces of the waste tire once crushed by the crushing device are repeatedly crushed until the wire is removed from the crushed pieces to about several millimeters because the wire is contained therein, and finally, The rubber is separated from the wire by making it into a chip shape. this is,
This is because the inclusion of the wire W in the rubber deteriorates the quality of the recycled product (rubber as a raw material).
It is desirable that the reclaimed product does not include wires in rubber as much as possible.
