Get PriceDec 01, 2004 A total scale-up method for planetary mill is discussed in this section. All parameters ( d M, h and R) of the basic planetary mill were scaled-up as t p times to investigate the effect of the scale-up ratio on E i. The scale-up ratio was changed from 0.50 to
This accurate scale up is different than scale up for ball mills or other stirred milling technologies. In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball mill. Additionally while techniques like
Get PriceThe performance and efficiency of ball mill generally improves with increasing diameter. All other factors being the same including media size, percent of critical speed, product loading, etc. The rule of thumb for mill scale up is approximately 1-(√D/√d) where d is the diameter of the smaller mill and D the diameter of the larger mill

Get PriceThe mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. 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
Get PriceDec 18, 2013 In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al.[19,20] found a scale-up factor for the Isamill of exactly 1, while Gao et al. imply that the scale-up factor for SMDs is
