01/02/2016· For particles above the critical size the discharge rate progressively reduces. Inspection of the ball mill classification data found that the shape of the classification function is similar to the Whiten expression for corrected efficiency to overflow (Fig. 1b, refer to Napier-Munn et al., 1996). Therefore the Whiten efficiency equation was adopted to describe the ball mill classification function

Ball mill media optimization - Metcom Tech

As shown below, “mill energy specific cumulative grinding rates” can be calculated for all screen sizes from mill specific energy input (kWh/t) and mill feed and product size distributions (Hinde, 1999; McIvor and Finch, 2007; McIvor et al., 2017). These include the mill grinding rate through the size of interest, calculated independently as above. Media sizing Ball mill media optimization ...

Ball Mills - Mineral Processing & Metallurgy

If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods, secondary ball mill with 25—40 mm(1″—1½”) balls and possibly tertiary ball mill with 20 mm (¾”) balls or cylpebs. To obtain a close size distribution in the fine range the specific surface of the grinding media should be as high as possible. Thus as small balls as possible should …

Optimization of mill performance by using

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

Ball mill Circuit output specific grinding rate = of fines (t/h) (t/kwh) Effective mill power draw (kw) We can then define the grinding efficiency of a ball mill as the ratio between the specific grinding rate of the coarse solids in the ball mill and the grinding rate (grindability) of the ore in a standard laboratory

Analysis of ball mill grinding operation using mill power ...

01/03/2014· Analysis of a large amount of batch ball mill grinding data available in the literature has shown that the values of the power specific absolute rate of grinding of the topmost size fraction, S *, and the power specific absolute rate of production of −100 mesh fines, F *, are not independent of the mill operating conditions and mill diameter. In general, both the parameters exhibit a significantly …

Estimation of Extraction Rate of Yttrium from Fluorescent ...

The relation between the extraction rate and the specific normal impact energy can be expressed as a straight line, irrespective of the milling conditions, and it is applicable to estimation of the extraction rate using a large-scale planetary ball mill. Therefore, the extraction rate of Y would be estimated by the specific normal impact energy of the balls calculated from the computer simulation.

TECHNICAL NOTES 8 GRINDING R. P. King

The tumbling action is difficult to describe accurately but certain regions in the mill can be characterized in terms of the basic pattern of motion of material in the mill. The motion of an individual ball in the charge is complicated in practice and it is not possible to calculate the path taken by a particular particle during station of the charge. However the general pattern of the motion
