They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.
Mar 08, 2013 calculation of ball mill grinding efficiency. dear experts . please tell me how to calculate the grinding efficiency of a closed ckt open ckt ball mill. in literatures it is written that the grinding efficiency of ball mill is very less [less than 10 ].Mathematical simulation studies of the mill grinding process are used widely for optimized structure parameters design [5,6]. Discrete element method (DEM) are always used to analysis the balls’ motion. Finite element method (FEM) are always used to analyze ball mill shell and the inside lines.
220.127.116.11 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 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 20–40 water by weight.Design Safer Chemicals Planetary ball mills 9 . Vibration Mills 10 . Mixer Mill MM 400 11 Feed material hard, medium-hard, soft, brittle, elastic, fibrous Material feed size ≤ 8 mm Final fineness ~ 5 m Setting of vibrational frequency digital, 3 - 30 Hz (180 - 1800 min-1).
