Converting A Ball Mill From Overflow To Grate Discharge

Converting A Ball Mill From Overflow To Grate Discharge

Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7-25 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25 . Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.Basically VRPMs are installed before one or ball mills for pre-grinding of the material so as to reduce the specific power consumption and increase the grinding capacity of the circuit. We have developed and designed systems to achieve up to 90 increase in capacity and reduce the power consumption by 5 KWH T to 7 KWH T.

Factors That Affect Ball Mill Grinder Capacity And Quality

Factors That Affect Ball Mill Grinder Capacity And Quality

Apr 24, 2018 The calculations indicate that in order to obtain overload with smaller mills at a constant circulating load, the L D ratios would have to increase progressively from the initial 1.2 1 value for a 5.5 n diameter mill, to a 6.8 1 L D value for a throughput reduction to 10 percent of the original value. This high an L D ratio is without precedent.For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,.
