The working principle of the SAG mill and AG mill is basically the same as the ball mill machine, but the barrel diameter of the SAG mill and AG mill is larger. The raw ore enters the AG mill through the feeding inlet, and the material is brought to a high place under the rotation of the barrel and then falls.
