In grinding, operating Efficiency compares the operating work index of a comminution machine to the Bond work index from bench scale crushing and grindability tests or/and pilot plant tests. Economic Efficiency is comparing the income from production to the planned income from production. Energy as consumed in comminution machines and the required energy as determined, from bench scale ...

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 ...

25/08/2020 Mat circulating load factor is computed for raw-mill and cement-mill at a sep efficiency of 90 and 70% for target residue 16 and 1% respectively on 90 microns sieve. This is observed, to maintain an acceptable circulating load factor between 1.5 to 2.0, a target mill discharge residue on 90 microns sieve would be 40–50 % for raw grinding and 10–20 % for cement grinding.

Ball mill rotating speed: when grinding ball adding rate remains constant, the useful power of ball mill varies with the rotating speed, therefore, production efficiency will also be influenced. Ball mill rotating speed need to be adjusted according to different types of ores. If the motor power is large enough, increasing rotating speed properly is an effect way to improve production.Usually,

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 ...
