CONSTRUCTION. CMI Technical Services reputation has been built from its ability to deliver Ball Mill installations with a high degree of quality that ensures the Mills consistent availability during key ore commissioning phases, thus ensuring a solid move into commercial production .

It is important to note that the Bond Ball Mill Work Index on SAG ground ore is similar to but not the same as a crushed Bond Ball Mill Work Index. It is ~ 7% higher because the SAG mill grinds the softest components quickly and leaves the harder material to be ground in the ball mill. Figure 3 presents the graph of SAG pinion energy vs. BWi.

SAG and the ball mill circuits (JKMRC, 1996). The phantom cyclone is used to classify the AG/SAG mill product into two products; the phantom cyclone overflow that is similar to the final ball mill product, and the phantom cyclone underflow is then used as an adjusted ball mill feed for the ball mill .

Mill (grinding) – Wikipedia, the free encyclopedia. Wi is the work index measured in a laboratory ball mill . It is similar in operation to a SAG mill as described below but does not use steel balls in the mill.

Some large SAG mills have what we call a "wrapped" motor drive, which is the motor fields are installed surrounding the entire circumference of the mill, with the mill itself being the stator. There are are different types of grinding mills: SAG which grinds using water. Autogenousl Mills which are dry. Ball Mills which do fine grinding

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill-ball circuit. All of the above contributes to

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

the ball scats from a single-stage SAG mill. These scats are non-spherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t. Surveying and modelling the mill revealed that the breakage rates had increased dramatically at the coarser end of the size distribution.

length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous (SAG) Mill via an utilized method. Miduk SAG Mill circuit is shown in Figure 1. Figure 1: Diagram of Miduk Copper Complex SAG Mill .

Use this online formula to calculate a Ball Mill, Rod Mill or SAG Mill Operating Work Index. Based on Fred Bond's work you can estimate the energy used into your grinding circuit. This is the most accurate and informative method, but much of the data necessary for its application is not yet available.
