how to calculate grinding media sizes for ball mill
We draw your attention, a larger grinding balls need to use for future loads. As practice shows, the difference between the grinding balls average diameter in mill and loaded grinding balls diameter is 10-15 mm. In our example, the grinding balls diameter needed to load into the mill must be equal to 40-50 mm. Lets sum up.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by
