[0035] Working principle: The utility model designs a ball mill. Since an inner lining plate 4 needs to be set in the ball mill to protect the inner wall of the ball mill, the device mainly reduces the number of bolts used on the inner lining plate 4 by setting a fixing structure 5. This is because the bolts are prone to collide with the grinding balls 17 and cause wear. At the same time, the setting of the fixing structure 5 can further fix the inner lining plate 4. Moreover, a large amount of debris is easily generated during the grinding process, and manual cleaning is time-consuming and labor-intensive. Therefore, the device is provided with a water spray pipe 13. The water spray pipe 13 cleans the inside of the machine body 3 by spraying cleaning liquid into the machine body 3, and then the sewage is discharged through the sewage pipe 15. Therefore, the utility model designs a ball mill, which not only improves the stability of the inner lining plate 4 in the ball mill, but also facilitates the cleaning of the inside of the ball mill.
