Correction factor: F5 For low reduction ratio R, for ball mills: F R. This correction is applicable when the reduction ratio, i.e., ratio of feed size to product size is less than 6. The multiplying factor for different values of F 80 /P 80 is determined from the expression F R = 2 R − 1.35 + 0.26 2 R − 1.35 or (3.39) F R = F 80 − 1.22 PTubular Ball Mills ScienceDirect,A survey of 40 industrial mills in Australia found that the maximum ball mill diameter in use was 5.34 metres and length 8.84 metres . Autogenous mills range up to 12 metres in diameter. The lengthtodiameter ratios indicated in Table 7.1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1

The calculation of d ij includes the aforementioned S and B functions, which can be determined in a laboratory batch mill. However, these parameters are sensitive to milling conditions such as the mill rotational speed, ball filling, powder filling, mill diameter, and ball diameter. As the size reduction ratio increases, the optimum ballEffect of Milling Parameters and Milling Energy on ,Amorphization via high energy ball milling is a solid state processing technique in which continuously moving balls transfer kinetic/impact energy to the powder particles. It leads to welding, fracturing, fragmentation and rewelding of the particles. During ball milling, nonequilibrium phases such as supersaturated solid solution, metastable

(coefficient of reduction), the work index of the material, the mill shaft power and the specific gravity of the material. These parameters are thoroughly studied in [4, 5] and an empirical relation is suggested expressing the mill capacity as a ratio of the mill shaft power and the energy consumed in the grinding process.The Effect of Ball Size Diameter on Milling Performance,size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 monosizes namely 8 mm +5.6 mm, 4 mm +2.8 mm and2 mm +1.4 mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted.
