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

The production capacity of the Rebar Mill was increased to 1.2 million tons per year; and the Wire Rod Mill to 0.7 million. A Rebar Mill with an annual production capacity of 0.8 million tons was added. A combined rebar and wire-rod mill with an annual production capacity of 0.5 million tons was added. The capacity has been

F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
