Although it was developed nearly 50 years ago, Bond 's method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency
Get Price26.12.2017· Mill Geometry And Speed 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.

Get Price25.10.2017· 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 length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction
Get Price13.09.2017· In "Crushing and Grinding Calculations", Bond identified correction factors that should be applied to the calculated power (W) determined by using the Bond Equation. The operating efficiency of production circuits can be measured using the following comparison: Efficiency
Get PriceJet mills can grind materials with low melting points effectively because these mills have intrinsic cooling due to compressed air expan-sion in the body of the mill. With the help of sweeping air, hammer mills may also be able to process materials with low melting points for coarse grinding applications. Explosibility. The risk of dust explosions must be taken into account when a material is
