The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

3) AG mill and SAG mill. The autogenous mill uses the ore itself as the grinding medium, which saves a lot of grinding balls and avoids product pollution. The feed size is 250~350mm. After one grinding, the product size is between several millimeters and 50μm. The autogenous mill has a large crushing ratio, which can replace medium and fine ...

Rubber liners absorb the impact of the larger grinding media and thus protecting the mill structure and prolonging it's life. Weight: Rubber weighs about 15% of an equivalent volume of steel. This means that a rubber liner system reduces the load on the mill structure and also reduces the basic power draw.

For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

The autogenous mill can directly add the raw ore or the uncrushed ore in the quarry to the autogenous mill. It can grind the material at one time, which accounts for more than 20% ~ 50% of the total product. The crushing ratio can reach 4000 ~ 5000, which is more thanten times higher than the efficiency of the ball mill and the rod mill.
