SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost ...

The EPA Responds. The vermiculite mining operation was finally closed in 1990. In 1999, the EPA sent an Emergency Response Team to Libby as a response to local health concerns and related national news articles about asbestos-contaminated vermiculite. The EPA assessed the risk to public health and then began taking actions to reduce the risk.

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 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

In conventional mills the diameter of the mill is smaller than its length. In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. This large diameter of mill is required to achieve the impact necessary to grind the ore.
