It is fed to the peripheral wall (32) of the dehydration tank (30) which rotates around the hollow shaft (15). At this time, the abrasive is brought into close contact with the peripheral wall (32) of the dehydration tank (30) by centrifugal force, and the hot air is blown toward the abrasive. As a result, warm air is blown into the entire dewatering tank (30) almost uniformly, and the abrasive can be dried in a short time.

In the abrasive cleaning device according to the second aspect of the present invention, after the abrasive is dried, the air in the hollow shaft (15) is drawn in through the absorption duct (61) to reach the tip of the hollow shaft (15).
