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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

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 is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
A bond is an adhesive material used to held abrasive particals together; relatively stable that constitute a grinding wheel. Different types of bonds are : (a)Vitrified bond, (b)Silicate bond, (c)Shellac bond, (d)Resinoid bond, (e)Rubber bond, and (f)Oxychloride bond.
