Factors Affecting Ball Mill Grinding Efficiency 2020 2 29 · The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a Mill Geometry and Speed Bond 1954 observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that . Comparison of energy efficiency between ball mills and 01/06/2009· Comparison of a laboratory IsaMill with a batch ball mill in open circuit showed that the benefit in the improved energy efficiency by using the IsaMill can only be realised when grinding to fine product sizes P 80 < 40 μm At coarser grind sizes the lab scale IsaMill using fine media is not as energy efficient as the ball mill probably because of the difficulty of breaking large feed . Ball mill media optimization Metcom Techplant ball mill s grinding efficiency Fig 1 The functional performance parameters mill grinding rate through the size of interest and cumulative mill grinding rates from both plant and small scale tests are applied to this task A plant media sizing methodology and . Ball Mills Industry Grinder for Mineral Processing The rotation speed is a key point related to the ball mill efficiency rotation speed too great or too small neither bring good grinding result Based on experience the rotat ion is usually set between 4 20/minute if the speed too great may create centrifuge force thus the grinding balls stay with the mill perimeter and don t fall In summary it depends on the mill diameter the larger
