parameters studied in this work are particle size, number of balls, time of grinding , particle density, and speed of the ball mill (rpm). An attempt has been made to develop correlation for the performance of the ball mill by correlating these variables with the grindability on the basis of . constant, and k is a correction factor.
Get PriceNov 24, 2017 Ball mill and rod mill are quite similar whether in external shape or working principle. In order to obtain better impact effect, some ball mill speed can be adjusted. Ball mill and rod mill are used to deal with various hardness of ore, rock and other materials whose particle size is not more than 60mm.

One of the objectives of this analysis is to determine the effect of process variables on the breakage rates of the various size fractions and on the ball mill power consumption. From this analysis, a

Get PriceA ball mill with a classifier will produce a fine product but the particle size distribution curve is very wide and when the correct average size is reached the number of fines is usually too high. Ball mills can be lined with ceramics to reduce contamination from abrasive products but there is constant wear of the media, which

In order to investigate effects of feed size and flow rate on the mill efficiency, feed particles size were changed in four different levels and flow rate was
Get PriceIn addition, Attritors offer the advantage of being able to take samples at any time and making formulation adjustments during high energy ball milling. Alternatively , ball mills are closed systems and do not offer these advantages. Nevertheless, ball mills can be a more appropriate choice for grinding larger sized material
