In fact, the product of a mill with 250 micrometer grate is finer than the product from the same mill with an overflow discharge. A useful feature of the MRRC grinding simulation package is that the effects of nondesign operating conditions can be easily tested. When the test ball mill is run in open circuit the design feed rate is ...

Ball mills with a drum length to diameter ratio greater than are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.

How a Grate Discharge Ball Mill Works Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

The principle of Grate Discharge grinding is nearly universally adapted in the cement grinding industry. Grate Discharge Ball Mills are the rule rather than the exception. Rod Mills for raw and finish grinding begin to enter the picture. Larger and larger diameter mills become common. Lengths tend to shorten.

Based on experience, millliner designs have moved toward more openshell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of :1 and :1.
