Effect Of Ball Size In Ball Milling

Effects of Ball Size and Particle Size on the Rate

Small zirconia balls in ball milling were effective to grind the powder to submicronmeter. In order to explain these experimental results on the milling rate, an equation for expressing the milling rate was proposed. The new equation is characterized by two parameters, ball size and particle size of the powder. The calculated and observed milling rates agreed well, and the effects of ball size

effect of ball size in ball milling

Effect of ball size and powder loading on the milling . 1/12/2013· As the rotation speed increases, kinetic energy of the balls increases, which, in turn, shifts the optimum ball size toward a smaller value. As the powder loading increases from 1 to 35 g at a given rotation speed and ball size, the milling efficiency decreases. Get Price

Figure 2 from The Effect of Ball Size Diameter on

An investigation was conducted to determine the effect of the ball diameter sizes on milling operation. A laboratory 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 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2 mm +1.4 mm for the experiment. A mill run having a mixture of

SAG Mill Ball Size Evaluator | Evaluation Factors

08.09.2013· SAG Ball consumption is "average" at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t. Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved. You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill. The ore is "hard" and "bulky". SAG liner/lifter design is good are the liners are made of

Factors Affecting Ball Mill Grinding Efficiency

25.10.2017· 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 speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for

Effect of Ball Size and Ball to Powder Ratio

28.12.2011· The variation of ball size in a planetary ball mill (PBM) was studied in terms of its effect on the specific impact energy of balls as a result of ball to ball and ball to vial collision calculated through a computer simulation. The mean crystallite size of calcium carbonate in the course of milling as well as the required time for obtaining a thoroughly formed calcium carbonate was also
