DISCUSSION According to Wills (2006), a combination of abrasive and impact forces between the particles and the milling medium, as well as the mill walls, can reduce particle size. In ball milling, spherical balls were the most common media form employed in the tumbling mill, however the spherical ball would eventually split owing to impact and other mechanisms inside the mill

Ball Mill Circulating Load - Mineral Processing &
Oct 09, 2015 The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of
