Factors Affecting Ball Mill Grinding Efficiency

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to120 C3 is the correction factor for mill diameter and is given as; 𝐶𝐶3 = 244 𝐷𝐷 02 (3) However, it is important to note that C3 =0914 vessel used in producing the ball mill was got from aDesign, Construction and Performance Analysis of a 5 Nevertheless, by increasing the ball filling ratio or the friction conditions, due to the presence of the mill feed, the dynamics of balls changed to a cataracting regime Finally, by insitu observations and using an image processing program, Rogachev et al [9] observed different types of ball movement depending on k Effects of the speed ratio on the efficiency of Figure 3a and 3b gives the results of the computer calculation The mill power at the pinionshaft for a 30% volume charge is the sum of: Figures 3a 3b give the power for an autogenous mill Figures 4a and 4b are for the same size mill with a ball charge of 6% of mill AG Autogenous SAG SemiAutogenous Mill Friction reduction ratio is the function of the average velocity of fracturing fluid, the gelled agent concentration, and the proppant concentration Based on the linear regression of 1049 experimental and field data, Lord et al put forward the following empirical formula to calculate the friction reduction ratio of HPG fracturing fluid (Lord, 1987):Reduction Ratio an overview ScienceDirect Topics
