Key properties of grinding media include composition hardness size and density some common types include alumina stainless steel yttria stabilized zirconia and sand ball milling will result in a ball curve particle size distribution with one or more peaks screening may be required to remove over or undersized
May 01 2014 it has been shown that mill capacity is linearly correlated to media surface area thus using 30 mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes however the fact that the coal feed to this plant is known to be contaminated with a
Nov 01 2015 for a makeup ball charge consisting of single ball sizes the mass distribution in the mill is given by 4 m d d 4 − δ − d min 4 − δ d max 4 − δ − d min 4 − δ where m d is the mass fraction of balls in the load which are smaller than d dmax is the largest ball size in the mill
