provides capital and operating cost estimates for each of the comminution circuits . The results showed that the HPGR - ball mill circuit achieved a 21% reduction in energ y consumption over the existing SAG - ball mill circuit at the same P 80 grind size of 160 m. At a grind of 80% passing 75 m, the HPGR

Ball Mill Design/Power Calculation

Jun 19, 2015 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 inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps

Grinding Mill Cost - 911 Metallurgist

Oct 14, 2018 The operating cost of a given grinding circuit is basically a function of the ore type. Energy is no longer a cheap commodity. While some British Colombia operations are fortunate to obtain energy at a very low cost (1.5 to 2 /kWh), some of the Southwestern U.S. operations are already paying approximately 4 /kWh

a 5 day week and 350 for a mine or mill operating continuously 7 days per week with only minor shutdowns or holidays per year. 6.3.2.2 Personnel Requirements Operating costs and capital costs are influenced by the num ber of personnel required to operate the mine, mill, and services

Estimated Water Requirements for the Conventional

further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and

other methods. The ball mill correction factor (CFnet) is empirical and one way of estimating it was presented by Amelunxen at the Procemin 2013 Short Course by Doll & Amelunxen. The SGI equation uses a transfer size between a SAG and ball mill; it is proposed that a synthetic transfer size of 2100 m be used to model single-stage SAG mills. 5.9ˇ

Ball Mill - 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
