However, in this paper, comminution efficiencies are based on the comparison of ball milling with single-particle comminution, either in terms of the energy to produce new surface or in terms of some size distribution parameter. If the energy to produce new surface by single-particle breakage is used as the basis for evaluating efficiency, then the efficiency of ball milling has a more ...

26/12/2017 According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times. The longer units are used for high retention ratios while shorter units are used where overgrinding is a factor to be considered.

• Ball mill grinding efficiency The circuit output is defined as the production rate of fines by the circuit. It is calculated from three values: 1. The dry ore feed rate to the circuit (t/h). 2. The % fines in the circuit feed. 3. The % fines in the circuit product. Use this equation to solve for circuit output: Circuit Fines in Fines in Circuit output = the circuit - the circuit x ore feed ...

More### What Factors Will Influence Ball Mill Grinding Efficiency?

In order to improve the ball mill grinding efficiency, a proper feed rate should be maintained so as to maintain a large amount of ore to be ground in the ball mill. If the feeding speed is too fast, the ball mill will be overloaded, the steel balls will be discharged, large pieces of ore and ore slurry will be discharged, or even blocked. Therefore, the ore feed must be continuous and even so ...
