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 ().
It is recognized as energy efficient grinding machine bringing substantial improvement in profitability of concentrators. Stirred Media Detritor (SMD), on the other hand, is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products.

It also greatly affects the paper machine's runnability. Optimal refining can also significantly impact mill energy savings. Valmet's refining system includes the most energy-efficient solutions for different refining and deflaking applications.
The separator, with the highest mill capacity, ensures high separation efficiency through having a low bypass to reject. An efficient separator leads to a number of benefits including low specific power consumption for the mill motor, low vibrations, energy savings due to minimal pressure loss, and optimised airflow.
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
