### Effect of circulating load and classification efficiency

The effect of circulating load and classification efficiency on the performance of ball mill circuits is compared to the effect on HPGR circuits. The fundamentals of grinding behavior are also

Live Chat### Addition of pebbles to a ballmill to improve grinding

Further tests were done using samples from a platinum mine namely the feed to a secondary mill (ballmill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 030% pebbles by volume with savings in energy and ball consumption increasing progressively.

Live Chat### CALCULATION OF BALL MILL GRINDING EFFICIENCY Page 1 of 1

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%]. please expalin in a n excel sheet to calcualte the same. thanks. sidhant. reply

Live Chat### Factors Affecting Ball Mill Grinding Efficiency

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 take this factor into account. As well mills with different

Live Chat### The energy efficiency of ball milling in comminution

Earlier 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.
