Oct 10, 2016 At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from classifier to the mill, it leads to mill overload. In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption

Ball mill. A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder

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

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight

Aug 10, 2020 Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder.
