Ball milling process was conducted in a planetary ball milling machine (QM-3SP04, Nanjing University Instrument Factory) equipped with four nylon ball mill tanks with an internal volume of 50 mL. The stainless steel grinding balls with the diameter of 6 mm, 8 mm, and 10 mm were used during ball milling.
Therefore, it is very important to master the reasonable ball loading quantity and the ball loading ratio of the ball mill in the process of using the ball mill. Selection of ball loading When a ball mill works, its efficiency generally depends on the sum of work done by each ball (number of impact times and impact force).
The law of ball size distribution in the horizontal planetary ball mill is studied by the discrete element method. The results show that the maximum impact energy could be acquired when filling rate is 24%, moreover the biggest mean contact force and the highest energy utilization ratio of balls could be acquired when the speed ratio is 1.5.
The effects of the ball-to-powder diameter ratio (BPDR) and the shape of the powder particles on EDEM simulation results and time in the planetary ball mill was investigated. BPDR was varied from 1 to 40/3 by changing the powder particle diameter from 8 to 0.6 mm.

The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and abrasive forces generated ...
