The design of the William Boulton Vibro-Energy Grinding Mill ensures the correct relationship between centre of gravity balance and the mode of vibration which causes the media to close pack. The packed mass of media slowly gyrates in the horizontal plane while in the vertical plane it rises in proximity to the outer wall and descends as it ...
Correlations for the Grindability of the Ball Mill As a - CiteSeerX. performance of a ball mill is measured with reference to the quantity of undersize or fines. (amount of grounded material passing through120 mesh screen) per revolution of the mill, collected for variation of each of the individual parameters.
3.3 Ball Size at Initial Ball Charge Ball sizes commercially available for charging in grinding mills range from 10 to 150 mm. The number, size and mass of each ball size used depend on the mill load and whether the balls are being charged for the first time to commence an operation or as replacements for worn out balls.

In practical terms, one must assume some mill diameter, usually about 150 mm (6 inches) less than the mill inside shell or nominal diameter, that allows for the difference between the mill inside diameter and the location of the centre of gravity of the ball, as well as an assumed liner condition midway between new and fully-worn.
The peripheral discharge type of Ball-Rod Mill is a modification of the grate type, and is recommended where a free gravity discharge is desired. It is particularly applicable when production of too many fine particles is detrimental and a quick pass through the mill is desired, and for dry grinding.
When the jar is full, the centre of gravity is again on the centre line of the jar. When the jar is 50% full, the centre of gravity will be BELOW the centre line (the axis of the cylinder). If you put the two rods rather close and the centre of gravity is above the plane containing the two rod, the jar will have a tendency to climb up *OR ...
