performance of ball mills grinding

How to Improve Ball Mill Performance

The energy specific grinding rate of the coarse material in the ball mill can then be defined as follows: Themill specific grinding rate reflects both the efficiency of the mill environment in breaking the coarse particles, aswell as the grindability characteristic of the ore over the particular size reduction range.

Factors Affecting Ball Mill Grinding Efficiency

a)Mill Geometry and Speed – Bond (1954) observed grinding efficiencyto be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and the …

The study results of the effect exerted by steel grade and heat treatment ofgrinding ballswith a diameter of 100 mm on the hardness, wear and impact resistance, as well as on the tendency to quenching crack embrittlement, are presented. The following effects have been studied: alloying carbon steel (0.6–1.5% of C) with 0.9–5.0% of Cr; 0.6–3.0% of Mn and 0.4–1.7% of Si, and for ...

Effect of RodMillFeed Sizing onGrinding Performance

There is no reported evidence that feed size has any effect on rodmillpower draw. Because the solids in the rodmillare known to appreciably expand themillcharge (as observed in the charge level before and aftergrindingout themill), there would likely be a tendency for power draw to be lower with coarser feeds and at higher feed rates. However, loss of power draw due to “overloading ...
