C O N S U L T I N G L T D TECHNICAL MEMORANDUM

Many people refer to “the” Bond work index when they really mean the Bond ball mill work index. There are two other Bond work index measurements commonly used: the rod mill work index and the crushing (low-energy im-pact) work index. Figure 3: Rod mill for

Rod Mills, How Do They Work?

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio ...
