Ball mill A typical type of fine grinder is the ball millA slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls Ball mills normally operate with an approximate ball charge of 30%
In the past, when primary, secondary and tertiary crushers fed material directly to large ball mills, the energy efficiency of the concentrator was determined for the most part by the ball mill operation, whereas now the energy efficiency of a plant often rests largely on the SAG mill operation
Feb 20, 2020· The term "mill operator" is fairly broad and can refer to several types of jobs, but in general, this type of operator will be responsible for operating a mill within a factory, warehouse, farm, or other industrial setting The mill operator is responsible for running mill machinery, reading plans .
The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter (Figure 811)The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
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 .
