increases with top size with the media competency 6 rocks being at the top of the scale. The work index series ball mill rod mill and MacPherson autogenous and pilot plant tests require relatively more weight for a given top size because they are run until a steady-state is achieved which involves
- Ball top size bond formula calculation of the top size grinding media balls or cylpebs-Modification of the Ball Charge This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency
and with the decreased grain size the necessary ball size also decreases Olejnik 2010; 2011. For each grain size there is an optimal ball size Trumic et. al. 2007. The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding. In both
Dec 18 2013 The Bond top size ball formula can be used to estimate the media size required. No such standard formulas exist in fine grinding. Energy and media parameters must instead be determined in the laboratory for every new combination of operating conditions such as feed size media size and media
• A useful guideline for make-up ball size for a new circuit was provided by Bond 1958. B F80K0.5 x WI x SGCs x D0.513 3 In the historical British units B Recommended make-up ball size inches. F80 Circuit feed 80 percent passing size microns. K A constant 350 for wet overflow mills etc.
Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill Coghill and DeVaney 1937 defined the ball size as a function of the top size of the feed i.e. d †V 0.40 .

Jul 01 2003 Figure 3 depicts the effects of media size on grinding times. From this plot it is shown that a target fineness of 80 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes the target grind is achieved in only 150 minutes.

Grinding media size calculation methods 4 replies in calculating the top size of grinding media for a ball mill there are 2 methodsformulas Fred C. Bond and AZZARONIs. Am looking at a ball mill F80 1248um and 8m diameter 78 Cs BWi 14.3 and SG 3. Azzaronis ball calc is almost 2X the Bond.
Sep 01 2013 Fig. 5 shows the equilibrium ball size distribution from various portions of three make-up ball size classes 50.8 mm 35.9 mm and 25.4 mm. The minimum ball size in the charge was taken as 12.7 mm in this example. For a single size of make-up balls the ball size distributions exhibit a mono-modal size distribution with a mode close to the .
