ball mill grinding efficiency theory

The following are factors that have been investigated and applied in conventionalball millingin order tomaximize grinding efficiency: a)Mill Geometryand Speed – Bond (1954) observedgrinding efficiencyto be a function ofball milldiameter, and established empirical relationships for recommended media size andmill speedthat take this factor into account. As well,millswith different length to diameter ratios …

May 22, 2019·Grindingoccurs by contacting the surface of theballwith the powder. Therefore, in the rollingball mill, thegrinding efficiencyis increased as theballdiameter decreases. It has been proven that the highestgrinding efficiencycan be obtained with a smallballof .mm diameter.

Factors thatEffecton theEfficiencyofBall MillTheball millis the core device used togrindmaterials after the crushing process. There are many factors that will make mucheffecton the workingefficiencyof theball mill. Here we will list some factors for users to notice in their later operation of theball mill.

Theefficiencyof thegrinding circuitis. 100(Wi/Wioc) =Grinding efficiencyin percent.....(3A) The multipliers for theefficiency factorscan be determined from the following: EF1 Drygrinding- for the same range of work aswet grinding,dry grindingrequires 1.3 times as much power as wetgrinding.

In determininggrinding efficiency, each stage is considered as a single stage. The power per tonne for rod milling is determined from therod mill feed rateand the power per tonne forball millingis determined from theball millfeed rate.

Themill efficiencyis then deduced in the same way as previously and it is seen that themaximum efficiencyis reached when the value of V is about 30%. It must be pointed out, however, that the reduction of the quantity of powder in themillleads to an increased rate of metal wear.

When the proportion of pebbles in themillcharge was low (up to 30%), the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate. This could be due to size segregation in themill. CITATION. Nkwanyana S and Loveday B. Addition of pebbles to aball-mill to improve grinding efficiency.

Thegrindingcircuit used for processing of gold, platinum and base metal ores typically consists of SAG primarymills, followed byball-mills. The power drawn by theball-millsis about the same as that of the SAGmillfor high capacity milling circuits. Table 1 is an example of data for this type of circuit.
