The screening mechanism 4 separates the ceramic abrasive according to the particle size to ensure that the particle size distribution of the ceramic abrasive is uniform. The ceramic abrasive is then dried by a drying mechanism 6 to ensure the quality of the prepared ceramic abrasive. At the same time, it is sintered by a mixing mechanism 7, a pressing and molding mechanism 8 and a high-temperature furnace 9 to prepare a ceramic abrasive with high hardness, high toughness and high durability. A plurality of storage tanks 10 are provided to store a plurality of required ceramic abrasive raw materials.
