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 ().

The friction factor is maybe the most uncertain factor in the calculations. This is because the friction factor is not a measured parameter but it is a fudge factor. This fudge factor depends on other effects including mud system lubricity, pipe stiffness, cuttings beds, hydraulic piston effects and tortuosity [18] .
