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 ().

Cement mill Wikipedia

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Volume Load thecementgrindingoffice

The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).

Mill Steel Charge Volume Calculation

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or
