Nov 18, 2008· We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.
In above equations: 𝑣m: 3total mill volume (m ), 𝑁: number of balls which exist in mill, 𝐴𝑏: each ball abrasion (g), 𝐴t: total ball abrasion in the mill (g), 𝑣b: each ball volume (m3), 𝑓b: supposed ball filling percentage, A r: ball abrasion rate in the mill. If above calculation were done again for 𝑓b
To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of A multicompartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is
performance equation (McIvor et al., 1990), the absence of a performance parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
