It appears, however, that the rate of ball and liner wear is greater in wet milling so the decision between wet and dry operation is, in cases where the choice is permitted, a matter of balancing the economic gain arising from reduced power demand and increased throughput against the increased cost of replacement of the ball charge and the mill ...
Analysis of a large amount of batch ball mill grinding data available in the literature has shown that the values of the power specific absolute rate of grinding of the topmost size fraction, S *, and the power specific absolute rate of production of −100 mesh fines, F *, are not independent of the mill operating conditions and mill diameter ...
The kinetics of batch dry and wet grindings of calcite, barite, quartz, lignite and anthracite from feeds of sieve size 425+300 μm has been determined using a laboratory scale ceramic ball mill.
Further, ball mills are divided into dry type ball mill and wet type lattice ball, according to different raw materials and discharging methods. These are especially used in mining industry to grind various ores and rocks in metal and nonmetal mines, either wet or dry as per the requirements. Ball Mills Market: Trends and Drivers
