Working Principle Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the

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.

Rod Mills How Do They Work Mine Engineer

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition and broken and worn rods must be removed. Rod mills usually require greater operator attention. It

Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced.
