[0029] In this embodiment, a conical material guide plate 9 is fixedly connected to the top of the sphere 3, and the conical material guide plate 9 is sleeved on the spiral shaft 5. The conical material guide plate 9 corresponds to the feed hopper 8.

[0034] Working principle: When in use, the raw materials are transported into the ball sleeve 2 through the action of the feed pipe 14 and the feed hopper 8, and the raw materials are made to slide between the ball sleeve 2 and the ball 3 through the action of the conical guide plate 1 9; then, the gear 1 72 and the gear 3 74 are driven by the motor 71, and at the same time, the gear 1 72 and the gear 3 74 respectively drive the circular tube 4 and the spiral shaft 5 to rotate through the transmission of the gear 2 73 and the gear 4 75, and at the same time, the circular tube 4 rotates with the ball 3, so that the grinding layer 2 18 on the ball 3 and the grinding layer 17 on the ball sleeve 2 grind the raw materials. In this process, the ground raw materials slide onto the conical guide plate 2 10 through the action of gravity and as the gap between the ball 3 and the ball sleeve 2 gradually narrows; at the same time, the feeding characteristic of the spiral shaft 5 is achieved. The raw materials are slowly pushed downward, thereby preventing the raw materials from moving upward and being blocked, and facilitating the grinding of the raw materials; the ground raw materials are moved toward the hollow ring 11 by the action of the conical guide plate 2 10, and the air flow is discharged through the air outlet on the hollow ring 11 by the drive of the fan 12, and the white corundum production materials enter the powder classifier 13 under the drive of the rising air flow, and the white corundum production materials are screened by the powder classifier 13. The materials that meet the requirements will be discharged from the discharge pipe 15 with the air flow, and the materials that do not meet the requirements will enter the feed hopper 8 from the opening at the upper end of the feed hopper 8, and the materials will be ground again. At the same time, the materials that are not carried away by the air flow will fall from the gap between the hollow ring 11 and the casing 1, and be discharged through the confluence trough at the lower end of the casing 1, and the discharged materials will be transported back to the feed hopper 8 by an external elevator for grinding again.
