Special ceramic materials for crushing equipment are non-metallic fine materials, commonly including alumina, zirconia, etc. Ceramic materials have high hardness and strong wear resistance, making them very effective for processing high hardness materials. In addition, ceramic materials also have characteristics such as corrosion resistance, acid and alkali resistance, making them suitable for processing materials with high purification requirements.
