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 ().
Here is a Table to help or show you how to estimate the cost of building a mine in today's market. You can roughly estimate how much is the cost of building a new mine by its rated capacity.
