Calculation Of Energy Required For Grinding In A Ball

The bond work index, w i, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of grinding product, the value of the work index w i.

Large Ball Mill Scaleup Factors To Be Studied Relative

Ball mills 5.5 m 18 ft in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40 by volume ball charges.This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.

The Energy Efficiency Of Ball Milling In Comminution

On this basis, taking 0.02 m 2 j the average value for single-particle breakage by compression loading as the baseline for efficiency calculations, ball mill efficiency for producing new quartz surface is around 15.Similarly, in ball milling soda-lime glass, using the calculated surface areas from the single-particle experiments of.
