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

How to Reduce Steel Consumption in Grinding Mills

Aug 26, 2017 In the tumbling mills (autogenous, semi-autogenous, rod and ball) wear is generally expressed in terms of steel consumption per ton of ore ground or per kWh consumed by the mill. When comparing the wear rate of different ores in different types of mills

Mathematical model of ball wear in grinding mills I. Zero

Mar 01, 1986 Effect of an increase of the ball feed rate on the steel consumption in a ball mill (O/Ol = 1.16). 94 a = -2.226 X 10-2 mm/h and a ball recharge of 50% 76.2 mm (3 in) and 50% 50.8 mm (2 in). Changes in make-up ball size and ball quality give similar transient response: steel consumption decreases rapidly down to a minimum value with a further

Improving The Efficiency Of Fine Grinding Developments

The high energy efficiency of stirred mills compared to ball mills is well understood within the industry. The use of tower mills as an energy The consumption rate of these media types was very high (higher than silica sand) due to inconsistencies throughout the

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.

Estimating Ball Consumption Molycop

Sep 17, 2018 For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill.
