  • Ball Mill Grinding Theory Crushing Motion/Action Inside

    · 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 Then the total energy possessed by the particlesFor overflow ball mills, the charge should not exceed 45% of the mill volume For grate discharge mills, the charge should occupy about 50% of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, ie,AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill
