Overflow VS Grate Discharge Ball or Mill Why Retrofit

24/06/2015 The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution. There is no complicated mechanical arrangement

13/02/2017 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. The drawings show the arrangement of the peripheral discharge. The discharge consists of

K is a calibration constant that varies with the type of discharge. For overflow mills K = 7.98 and for grate mills K = 9.10. This difference is ascribed to the presence of a pool of sl urry that is present on the bottom of overflow-discharge mills but not to the same extent in grate-discharge mills.
