In a method for disposing of waste matter such as waste tire pieces by using first and second shredding members each having shredding blades, the waste matter is introduced into a space between the shredding blades of the first and second shredding members and shredded or torn off into fine chips by operating the first and second shredding members, while partially caught by grooves formed in opposite faces of the shredding blades of the respective shredding members. By moving the first and second shredding members relative to each other in opposite directions to impart a shearing force to the waste matter in the space between the shredding blades, the waste matter is effectively torn off into pieces. When a waste tire is processed in an apparatus for practicing the method, it is successfully separated into rubber parts and wires with high efficiency.
A method for disposing of waste matter by relatively moving a first shredding member and a second shredding member, said first and second shredding members having shredding blades provided in their opposite faces with grooves, comprising placing said waste matter in a space between the shredding blades of said first and second shredding members, and catching parts of said waste matter by said grooves formed in said shredding blades in shredding said waste matter with relative movement of said first and second shredding members, said grooves being open to said space.
An apparatus for disposing of waste matter, comprising a shredding section including a first shredding member and a second shredding member, at least one of said first and second shredding members being movable relative to the other, said first and second shredding members having shredding blades for cooperatively shredding the waste matter, said shredding blades of said first and second shredding members being opposite to each other to form a space therebetween for accommodating the waste matter to shred the waste matter with said shredding blades and having opposite faces with grooves for permitting the waste matter to be partially caught.
