involve grinding). With Lloyd''s ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd''s research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level to ...
mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.
