    Different combinations of SAG mill ball charge and grate open area were tested until 2006. A higher load level was achieved after several changes in the grate design that prevented both liner and grate breakage. Upon resolution of issues related to the mill grate design, the project achieved the target throughput of 41 kt/d. Phoenix Transport of slurry through the mill is described by a function which relates the hold-up of slurry, grate design, grate open area and mill speed to the volumetric discharge rate through the grate (Morrell and Stephenson, 1996) Jp = k Q0.5 g-1.25 A-0.5 f0.67 D-0.25 (7) where.

    However, the curved design necessitates redrilling of the mill head and also requires curved grates, which can be quite complicated compared to a simple radial design. The best way to eliminate material problems is to use a grate, peripheral discharge trunnion supported mill or use a grate, open-ended discharge shell supported mill.

    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 Many grates in operation are pegged by grinding media to varying degrees of severity. This paper introduces a comprehensive, accurate and rapid method to measure and track the size and pegging status of each and all grate holes in situ, and therefore provides tracking information on the Open Area of a SAG mill.

However, the range of open area they covered was from 0.5 to 2 per cent of the total grate area, which is much smaller compared to the normal operating range (Napier-Munn et al., 1996). All AG and SAG mills use steel or rubber grates to hold back the grinding media, Considering the shortened mill length (from 3.66 to 3.48 m), smaller grate hole size (from 26.8 to 18.5 mm) and reduced grate open area (from 10.47 to 8.16 ), the load volume is expected to be more than the pre-installation condition for the same feed rate.

    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.
