The grinding method of the dry grinding device for slag treatment according to claim 8, characterized in that: The steps include: The first step is to feed the material to be ground into the feeding assembly (7), start the power mechanism 1 at the outer end of the feeding assembly (7), and drive the feeding assembly (7) to start, so as to transport the slag material to the ventilation processing assembly (9), start the external air supply mechanism, and input the pressurized air into the interior of the ventilation processing assembly (9); Step 2: As the feeding assembly (7) rotates and feeds the material, the material falls into the ventilation processing assembly (9) from multiple locations, and the compound rotating assembly (5) is kept rotating, the compound rotating assembly (5) drives the material shifting assembly (6) to rotate, and when the compound rotating assembly (5) is connected to the ventilation processing assembly (9), the internally purged pressurized air purges the material in the ventilation processing assembly (9), the slag material is gradually dried, and the moisture is purged out of the outside of the fixed cylinder (2); Step 3: When the composite rotating component (5) rotates and is closed with the ventilation processing component (9), the connecting port (53) is connected with the discharge port (94), and the pressurized air in the ventilation processing component (9) sweeps the internal slag downward and drops it into the fixed cylinder (2), and the vertically downward pressurized air sweeps the accumulated slag at the bottom of the inner cavity of the fixed cylinder (2), so that the slag is dispersed to both sides, and at the same time, the powder that is ground to meet the size is swept out toward the discharge hole (3) below.
