Ball Mill Design/Power Calculation
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ...
Ball Mill Equation - my-next-proberaum.de
Ball Mill Equation In a typical grinding circuit ore is fed into the mills where abrasion, attrition and impact reduce its size. usually, the grinding circuit contains at least two interconnected mills with material classifiers e.g. cyclones separating the fine material from the coarse that then goes for regrinding.
Ball Mills - an overview | ScienceDirect Topics
It is possible to make an approximate calculation of the capacity of a ball mill by means of the equation: N = ( 0.104 D 3 L ρ b .ap ϕ 0 .88 + 0.1 L n ) 1 η 1 η 2 where ρ b.ap is the apparent density of the balls; l is the degree of filling of the mill by balls; n is revolutions per minute; η 1, and η 2 are coefficients of efficiency of electric engine and drive, respectively.
