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 ().

In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks.
The mill has an internal mechanical classifier to perform the particle sizing, and it is easy to change the particle cut required. The oversized material is rejected from the classifier wheel within the mill and returned to the grinding section of the mill for further size reduction.
Nowadays, grinding mills find massive applications in the mining industry across the globe. Grinding mills are specially designed for handling mining operations with high-level hardness. When operating under the mining industry, a grinding mill helps you to produce a perfect size. Grinding mills need less maintenance and downtime while operating.
mill grinding rate of coarse material is then calculated. At the circuit target P80 size, this is the mill grinding rate (of coarse material) through the size of interest. The objective is to maximize this rate. The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material's grindability
