ABSTRACT Semi-Autogenous Grinding mills can be optimized for maximum ore throughput or maximum grinding energy efficiency. In both cases, precise control of the mill weight is critical.

AG and SAG mills are now the primary unit operation for the majority of large grinding circuits, and form the basis for a variety of circuit configurations.

A Dam Glossary - Bureau of Reclamation Homepage. Dam. A barrier built across a watercourse to impound or divert water. A barrier that obstructs, directs, retards, or stores the flow of water.

SAG mills are often flexible enough to accomplish the same size reduction provided by two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. With units available in ratings up to 35,000 hp, capable of supporting a grinding line that can output more than 100,000 mt/d, SAG mills have played a steadily growing role in mineral processing. To get an ...

Estimates the charge volume of a grinding mill based on the number of exposed lifters. By counting the number of lifters showing (during a mill shutdown) and comparing to the total number of lifters (including those buried in the charge) the fraction of the mill under the charge is determined.

A line drawing of the Fort Knox SAG mill liner configuration and spare liners awaiting installation. Five and one quarter inch steel grinding balls - cannon balls - occupy 8% of the mill volume and are consumed in the grinding action at the rate of 600,000 pounds per month.

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill, but not the weight of the mill itself. While many ...
