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 sintering.It 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

The charge inside the mill expands and contracts as the mill revolves. Hence, the center of gravity also keeps changing position. Moreover, the angular speed of the mill and mass of balls within the mill influence the profile of the cascading charge which results in the torque being a complex function of all the operating variables, not as simple as implied in many of the empirical formulae .

Ball Mill Power. From equation (8) it appears that Vb² = 16kgr² – 32k³gr4 + 16k5gr6, but the kinetic energy e = wv²/2g, or in this case, e = w(8kr² – 16k3r4 + 8k5r6), which is the energy possessed by any particle of weight w, and radius r, at the end of its parabolic path, which is …
