### Overflow Versus Grate Discharge Ball Mills: An Experimental

A set of experimental test work has been carried out in a continuous pilot ball mill of 0.41m X 0.56 m diameter X length at different mill speeds percent solids and discharge mechanism. The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of

### L / D Ratio in Overflow Ball Mill Design and Operation

Ball mill shape factors in the period prior to 1927 averaged 1.1/1 for 29 center discharge mills and 1.0/1 for 30 peripheral discharge mills. With the resumption of new plant construction after the 1930s depression the Morenci concentrator continued the 1/1 ratio with its 3.1 x 3.1 m 10 x 10 ft mills.
