  • Modeling breakage rates of coarse particles in ball mills

    01/06/2009· The non-first-order rates shown in Fig. 1 have often been associated to the fact that at coarser sizes particles are no longer properly nipped between grinding media, with softer particles breaking more readily, leaving tougher particles within the mill charge. This, which is called by Austin a ‘material effect’, contrasts with an ‘environmental effect’, by which breakage rates of all

    In primary ball milling, wear speed is largely independent of ball diameter and mill volume. (The same is true for secondary, tertiary, and regrind grinding.) In these applications, Equation 4 can be used to quantitatively predict how ball size and ball volume charges will affect wear rates. For example, a 5% increase in charge volume (42% versus 40%) will increase hourly ball consumption by 5

  • Ball Mills Or Vertical Roller Mills: Which Is Better For

    Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough top-size media to grind the mill feed materials. If not so, high, underground materials (referred to as nibs) will collect
