Ceramic ball wear prediction in tumbling mills as a grinding media selection tool

Comparison of alumina ball size distribution in two white cement grinding units using Swebrec function

“…Recently, [8] used a simulation that combined the milling circuits and the BSD to determine the best make-up ball charge applicable to a platinum-bearing ore. Studies performed by Austin et al [9] have been focused on the grinding performance through the very well-known selection function, which also has been used by Katubilwa and Moys [10] and Bwalya et al [11] to obtain the BSD in coal mills. In addition, modeling works for ceramic balls in tumbling mills were addressed by [12] and [13], respectively.…”

Ball size distribution for the maximum production of a narrowly-sized mill product

“…Several researchers have proposed make-up charge policies; the underlying idea has been to maintain a steady balanced ball mill charge. The following sequel of work indicates the important milestones achieved over the years: Austin et al [3]; Austin and Klimpel [4]; Menacho and Concha [5,6]; Austin and Concha [2]); Bwalya et al [7]; Cho et al [1]; and Rivera Madrid et al [8].…”
