The invention discloses a multi-stage step-by-step-type crushing device for
ceramic waste. The multi-stage step-by-step-type crushing device comprises a box body, an isolating net, a first partition plate and a second partition plate are sequentially arranged in an inner cavity of the box body from top to bottom, a
grinding cavity is formed in the top end of the second partition plate, and the inner cavity of the box body is partitioned into a crushing cavity, a pulverizing cavity and a
grinding cavity from top to bottom through the isolating net, the first partition plate and the second partition plate. A motor is arranged at the bottom end of the box body, a
motor shaft of the motor is fixedly connected with a rotating shaft, a charging hole is formed in the top wall of the crushing cavity, and a plurality of crushing rods are arranged at the top end of the outer
circular face of the rotary shaft in a circularly arrayed mode. A plurality of pulverizing rollers are arranged in the pulverizing cavity in a circularly arrayed mode, a
grinding disc is arranged in the grinding cavity, and a plurality of supporting legs are evenly arranged at the edge of the bottom end face of the box body. According to the multi-stage step-by-step-type crushing device for the
ceramic waste, by forming the crushing cavity, the pulverizing cavity and the grinding cavity and by utilizing the crushingrods, the pulverizing rollers and the grinding disc, multi-time and level-division crushing is conducted, through layer-by-layer crushing and grinding, homogenization of
ceramic fragments is achieved,the crushing quality is greatly improved, and the subsequent production requirement is met accordingly.
