[0054] The crushed kaolin enters the grinding box 1 through the discharge mechanism. Specifically, the discharge plate 14 is driven by the cylinder 16 to slide outward inside the chute 12, and the sliding distance of the discharge plate 14 is controlled, that is, the speed of the kaolin entering the grinding box 1 through the discharge port 13 is controlled;

[0055] The kaolin entering the grinding box 1 is finely ground between the grinding roller 19 and the grinding seat 18 under the rotation of the grinding roller 19. At the same time, the second electric heating tube 23 in the second drying mechanism heats the inner ring wall of the grinding seat 18, that is, the kaolin is dried for the second time during the fine grinding process, which has good drying effect and good grinding effect.
