by the mill. Figure 3 - Cone crusher performance curves Following the upgrades in the SAG mill circuit, sampling and modeling of the ball mill circuit identified a bi-modal hardness characteristic of the ore. Evaluation with both MetCom and JK SimMet lead to changes in the ball make up size from 75 mm to a 5050 mix of 75 mm and 38 mm.

articleosti901637, title Improving Energy Efficiency Via Optimized Charge Motion and Slurry Flow in Plant Scale Sag Mills, author Rajamani, Raj K and Delgadillo, Jose Angel, abstractNote A research team from the University of Utah is working to make inroads into saving energy in these SAG mills. In 2003, Industries of the Future Program of the Department of Energy tasked the ...

Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size.

Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary ...

Following crushing through a jaw crusher 3, the ore is fed into the semi autogenous grinding SAG mill 4 along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.

In this paper, the slurry transport problem is solved using the principles of fluid mechanics. First, the motion of the ball charge and its expansion are predicted by a technique called discrete element method. Then the slurry flow through the porous ball charge is tackled with a fluid-flow technique called the marker and cell method.
