초록
In this study, a method of shear crushing and a two-stage disk mill were introduced to grind the waste tirepowder. Rubber chips with various size were obtained during the crushing or grinding step. The two-stage diskmill was composed of two drum-type blades rotating at various speed and in opposite directions. Therefore, moreroughly surfaced particles of micronized waste tire powder were obtained using shear crushing rather than usingconventional cutting crushing. In this study, the shape of shear-crushed waste tire particles was compared withconventional cutting crushing particles by scanning electron microscope. In addition, the particle size analyzer wasemployed to determine the appropriate particle size of waste ground tire powders obtained in this study.
