So, we generally adopt sphere grinding media to process large sized raw material. The grinding process between columnar grinding media is line contact. At this time, the stress is concentrated and raw materials are easily to be ground. The contact area is large, so it is suitable for processing small sized raw materials. The grinding process between sphere grinding media and raw material is point contact.Shape of grinding media: At present, the common used shapes of grinding media are: sphere, short column, rod and so on.
