Grinding, or abrasive machining, is the process of removing metal in the form of minute chips by the action of irregularly shaped abrasive particles. These particles may be in bonded wheels, coated belts, or simply loose. Grinding wheels are composed of thousands of small abrasive grains held together by a bonding material.

Comminution may be carried out on either dry materials or slurries. 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 ...

Shaft furnaces use pellets (produced in the same way as pellets for the BF), or lump ore. Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4) from the siliceous gangue. The fine ...
