The 24' x ' Ball Mill The Copper Mountain ball mills are 7315 mm [24 feet] in diameter and 12040 mm [ feet] long. They are overflow discharge ball mills with inside diameters of 7315 mm [24 feet] and grinding lengths of 11887 mm [39 feet]. Each Ball mill is also driven by two 8,500 horsepower ABB motors.
SAG Mill Optimization using Model Predictive Control
Control of SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell,, van der Westhuizen,, Mainza, 2009).

The working principle of ball mill
· The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.

Semiautogenous and autogenous milling has become an integral component of modern mining operations. They allow large volumes of raw rock feed to be processed efficiently and cost effectively. Current semiempirical methods for the design of mills are based largely on data obtained from pilot and full scale mills.
Optimizing your SAG mill operation
· The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.
Mechanochemical activation of natural clay minerals: an ...
· Mechanochemical activation can be defined as a process able to induce structural disorder through intensive grinding. In certain conditions, it may increase the chemical reactivity of the processed material. The process is extensively utilized in extractive metallurgy, synthesis of nanocomposites or pharmacology. It is also considered an environmentally friendly alternative .
