Ball Mill Power Calculation Example#1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

The size of the ball mainly depends on the particle size of the material to be ground, and the diameter and speed of the mill can be considered appropriately. Formula (1-15) is an empirical formula for spherical diameter and feed size. dmax — The maximum diameter of steel ball, mm; amax — the maximum size of feeding granularity, mm.
Based on his work, thisformulacan be derived forballdiameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.

TheMillingProcess – Definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters ...

MillingSpeeds and Feeds Charts The most important aspect ofmillingwith carbide endmillsis to run the tool at the proper rpm and feed rate. We have broken these recommendations down into material categories so you can make better decisions with how to productively run your endmills.
Two-Product Formula. Given the mass and component balance equations : F = C + R. Ff = Cc + Rr. Mass yield (Y) can be solved as a function of the stream, assays which yields the two-product formula: R = F- C. Ff = Cc + r (F – C) Mass Yield Formula Example
Mainly in USA , the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.
