Coarse particles are held by the rods in the grinding machine for a longer time and thus are subjected to more grinding action. The rod mill process has a great selective grinding effect. The particle size of the grinding product is uniform, and the degree of overcrushing of the ore is light, so the rod mill can form a single-stage rod …
Additionally, when the downstream process involved grinding mills, the fines created from high-speed crushing circuit were a benefit to the comminution process. In general, if the feed material, application parameters, and downstream process match with the capabilities of a high-speed impact style crusher, this is the crusher type to use. ...
In mineral processing, grinding mills must endure vibration, shock loads, moderate to slow speeds and a high concentration of particulates.
