Selection of AC Induction Motors for Mining Applications Although motors may appear to be the least complicated component in the specification of mining equipment, this stone begins to demonstrate that mining applications present an immense matrix of application criteria to properly specify, design and build motors.
Metso supplies equipment, parts and services for mining and minerals processing around the world. We have +100 years of expertise in various mining processes, such as comminution, beneficiation, material handling, and pyro processing.
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 is maintained at 1.4 to 1.6.

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