Predicting Steel Media Consumption Grinding

Ball Mill Media (kg/kWh) = 0.0944*Ai^0.299. Aidan Giblet and J. Seidel published a paper on the 2011 SAG conference (MEASURING, PREDICTING AND MANAGING GRINDING MEDIA WEAR) and they obtained. Ball Mill Media (kg/kWh) = 0.0817x(Ai)0.498. the two equations are very similar.

Using Abrasion Index for calculating Steel Balls and mill

Just published is some Newmont data in a paper at SAG 2011 on both SAG and ball mill steel consumption. The ball mill wear data reflected a 0.5 factor on the Bond equation consistent with Arts observation above. I also like the Molycop equation Levi has discussed for ball mills although it does seem to reflect slightly higher wear rates than

Ball Mill Design/Power Calculation

Jun 19, 2015 If P is less than 80% passing 70 microns, power consumption will be; Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh

Ball Mills an overview ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
