The Effect of Ball Size Diameter on Milling Performance | OMICS .

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,.

Experimental Procedure

You are now ready to run the experiment in the laboratory. Open the Experimental Laboratories and choose the Batch Grinding experiment. The purpose of the grinding test is to obtain the particle size distribution at four different grinding times. To do this efficiently, load four identical ball mills and rotate all four on the rollers.
