Operating and Troubleshooting a Grinding Circuit

A ball mill operates more with the grinding surface action of the balls than the impact form of grinding that the rod mill uses. Taking this into account you can see that if the rod mill doesn't reduce the ore to a size that the ball mill can reduce quickly, the circuit load will climb until its volume is greater than can be handled.

Back to Basics Hammer Milling and Jet Milling Fundamentals

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill's internals is less of an issue.
