Example Embodiment
[0036] Embodiment 1 A kind of recycling method of waste and old refractory material, is characterized in that, comprises the following steps:
[0037] (1) Material selection: select waste high-alumina bricks for blast furnaces, waste silicon carbide shed slabs in the ceramic industry, box sand, ooze and waste first-class high-alumina bricks that meet the requirements;
[0038] (2) Coarse crushing: put the above-mentioned raw materials into a roller crusher for crushing, and the crushed materials are transported to a vibrating screen for screening by a belt conveyor, and the particles with a particle size of less than 10 mm are selected. The granular material larger than 10mm is returned to the roller crusher by the belt conveyor to continue crushing until the particle size is less than 10mm, and the coarsely crushed granular material is obtained;
[0039] (3) Fine crushing: send the coarsely crushed granules to the impact crusher for fine crushing to obtain fine particles belo...
