Abstract
A waste tire treating apparatus is disclosed. It includes a grinding device for grinding the waste tire into blocks with smaller volume, a washing device for washing the ground waste tire, a drying device for drying the washed waste tire, a granulating device for cutting and granulating the dried waste tire into granules with predetermined volume, a heating device for heating and melting the waste tire granules and a sorting device disposed under the heating device for receiving the molten rubber and nylon fibers and the steel filaments of the waste tire. The sorting device includes a channel with circulated water flow, whereby the mixture of the rubber and nylon fibers float on the water, while the steel filaments precipitate onto the bottom of the channel to be separately recovered.
