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 ...
WhatsApp: +86 18203695377Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust.
