Generally speaking, the selection of ball milling jar is mainly considered from hardness, corrosion resistance, pollution and vacuum grinding. First of all, the hardness of the sample needs to be smaller than that of the ball mill and the grinding ball. Otherwise, the sample will wear the ball mill jar and the grinding ball during the ball mill ...

Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...
