Ball Mill

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.
