WhatsApp: +86 18838072829Grinding machine has been widely used in gold mines in South Africa since 1905. At that time, the grinding machine used river pebble as the grinding medium, which was essentially a gravel mill. Later, in order to improve the production capacity of the mill, cast iron balls were used as the medium, so normal gravel mills were evolved into ball mills and rod mills.
WhatsApp: +86 18838072829In the order you have listed; a ball mill can fine grind down to <400 mesh if needed, a rod mill will efficiently grind to 150/200 mesh range, and a roll mill can do a +/ 100 mesh. The ball and rod mills are similar in appearence, as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium.
