The qualitative e ect of changes in ore size distribution (OSD) on the performance of the mill can be addressed using the grindcurves (Powell and Mainza, 2006) of the SAG mill under analysis. The operation of SAG mills is extremely sensitive to mill lling; from a qualitative point of view, for a given ll level and constant feed rate and
respect with SAG mills being increasingly less sensitive as the ball charge is increased Morrel S and Valery W 2001 22 EFFECT OF FEED SIZE DISTRIBUTION ON SAG MILLING The qualitative eect of changes in particle size distributions PSD on the SAG mill performance can be addressed by using the grind curves.

Grinding Mill Circuit narios were conducted to investigate the performance of the SAG mill with varying feed size, mill ball curve, size and shape distribution . ...
values may not necessarily match the specific energy required for an existing or a planned AG/SAG mill due to differences in the many operating and design variables such as feed size distribution, mill dimensions, ball load, ball size, grate/pebble port size, trommel .
of grate/pulp lifter design in AG/SAG mill discharge. The current understanding from literature lacks knowledge of mill content size distribution and its effect on discharge through the grate at various aperture sizes and radial positions. It also indicates that in order to advance the understanding in a meaningful way, a more mechanistic ...

A sharp grinding curve, characterised by a low ratio of P98 to P80 is vital . The energy ... The SAG mill grind curve begins to deviate from linear behavior by exhibiting ... charge, the size distribution curve of the ground product became steeper ...
Pebble removal decreases the abrasive overgrinding as reflected in the mill discharge size distributions (Table 4). Total grinding power consumption decreases and SAG mill capacity increases significantly. Later tests, with other types of ore, have shown lesser differences between those size distributions.
AG/SAG mill product that needs additional grinding in the ball mill, or "Corrected Ball Mill Feed." T2'' is the 80% passing dimension of the Corrected Ball Mill Feed. Figure 1. Comparison of the Particle Size Distribution Slopes Figure 2. Relationship Between the Transfer Size Distribution Slope and T 80 or AWi0/BWi Figure 3.
The form of the distribution curve was found to be primarily a function of the size reduction. The distribution function of the initial uniform sample is a delta function. As soon as any size reduction occurs, there is a transfer of material to a wide range of sizes thereby increasing the dispersion.
