Mill (grinding)

2019-10-2 · 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 ().

Ball mill media ball loading and ball size and mat. The load of the ball mill medium mainly includes the amount of ball loading and the size and proportion of the ball What are the basic requirements to be met The first is the calculation of the amount of ball loading on the ball mill media, that is, the percentage of the volume of the grinding media in the effective volume of the mill...

Rod mills, how they function

2012-11-26 · Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
