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

Comminution in mining -
Comminution is the most energy intensive process stage in the mining industry. It accounts for up to 40 percent of the total energy used in mineral processing operations. While the head grades are constantly declining, more sustainable technologies and solutions are required to process hard, variable and low-grade ore bodies.

The grinding media in a Rod mill are long rods of particular material which grind the ore by tumbling within the mill. The grinding action is by line contact between the long rods. There is a very minimal slime production since rods tumble and spin in roughly parallel alignment and produce size reduction of coarse ores efficiently.
