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 available for the purpose of crushing ore. ...
