The second stage dry open circuit grinding tests may show an increased Work Index because of ball coating, and are not reliable if ball coating exists. Use of the Work Index The Work Index can be calculated by Equation 1 from commercial crushing or grinding data or from pilot mill tests, and compared with the listed Work Indexes in Tables I and II to obtain the relative mechanical efficiency.

Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand, working animal, wind or water. Today they are usually powered by electricity. The grinding of solid materials occurs …

Mineral processing - Wikipedia
Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
Mineral and Mining Engineering: What are the differences ...
Crushing and Grinding are processes that work together to get the rock to be small enough so it can go to flotation. In flotation, they objective is to separate the valuable ore from the waste rock. Crushing is the initial stage of comminution (the action of reducing a material) in mineral processing.
