How Important is the Length of the Grinding Mill to Comminution . The relationship of mill diameter to length is of considerable importance. Rod mills should have a length greater than the diameter to avoid entanglement of rods. The construction of ball mills is different in that the diameter may be larger, equal to, or smaller than the length.Comminution  Wikipedia,Comminution  Hazen Research,This test determines the Bond Ball Mill Work Index, which can be used with Bond’s Third Theory of Comminution to calculate net power requirements for sizing ball mills. The test is a closedcircuit, dry grindability test is run in a standard ball mill, and can be performed at

Read MoreThe energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill. Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill, it became less so as grinding proceeded and for a product median size of 4.8 microns it was the same.ball mill principle of comminution  qniquequilter,Scaleup Theory of Jet Mills on Basis of Comminution Kinetics.,Get Price.

Read MoreEarlier work by Fuerstenau and Kapur on the comminution of quartz in a singleparticle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically.Comminution  SlideShare,Stirred mills represent the broad category of mills, which use a stirrer to providemotion to the steel, ceramic, or rock media. Both vertical and horizontalconfigurations exist, and since they can operate with smaller media sizes, theyare far more suitable for fine grinding applications than ball mills.A developed approach based on grinding time to determine,,A developed approach based on grinding time to determine ore comminution properties N.
