Gravel Mill

Description Inquire

The gravel mill can grind the material to -0.074mm at one time, and its content accounts for more than 20% to 50% of the total product. The crushing ratio can reach 4000-5000, which is more than ten times higher than that of ball and rod mills. Pebble mill is a new type of grinding equipment with both crushing and grinding functions. It uses the material to be ground itself as the medium, and achieves pulverization through mutual impact and grinding, hence the name of the pebble mill.
Pebble mills are designed for long life and minimal maintenance and are often used in second stage grinding in dry or wet applications. Gravel mills grind ores and other materials to 35 mesh or finer particle size in a variety of open or closed circuits.

Working Principle

The gravel mill can grind the material to -0.074mm at one time, and its content accounts for more than 20% to 50% of the total product. The crushing ratio can reach 4000-5000, which is more than ten times higher than that of ball and rod mills. Pebble mill is a new type of grinding equipment with both crushing and grinding functions. It uses the material to be ground itself as the medium, and achieves pulverization through mutual impact and grinding, hence the name of the pebble mill.
Pebble grinding is usually used for fine grinding, as secondary grinding equipment for rod grinding and autogenous grinding, and in individual cases, it is also used for coarse grinding. The structure of the pebble mill is basically the same as that of the ball mill, so when the ball mill in the existing concentrator is converted into a pebble mill, the structure does not need to be fundamentally changed. However, in order to maintain the original processing capacity of the concentrator, it is necessary to increase the volume or number of mills.
