Dry Type SAG Mill

The dry self-grinding machine/semi-self-grinding machine is a kind of equipment which uses the ore itself to crush and grind. The barrel has larger diameter, shorter length and larger feeding size, which can replace medium crushing, fine crushing and coarse crushing. Production Process. Generally, the amount of steel balls added from the mill is 2-3X of the effective volume of the mill, and the amount of steel balls added by the semi-autogenous mill is 10-1 2X of the effective volume of the mill. Since the amount of steel balls is small, the liner can be effectively reduced. The wear and the consumption of the steel ball are also small, and the grinding product has less pulverization phenomenon, and the iron impurities are reduced, thereby improving the beneficiation index and improving the quality of the concentrate.
