The Bond/Barratt models assume that the SAG mill product stream is a Bond-compatible size distribution, an the T 80 predictions are presented on this basis and the extra fines are ignored (however, the Optimized Bond/Barratt models ball mills do reflect the reduction in operating work index).
Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve.Overflow discharge mills give a final product in an open circuit.

particle size" can adequately describe a size distribution, but this implies expecting a response based on a calculated average (or mean). If forced to use a single calculated number to represent the mid-point of a particle size distribution, then the common practice is to report the median and not the mean. The median is the most

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
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.
Pebble removal decreases the abrasive over-grinding 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.
This approach formed the basis for the later standard JK drop weight test. In this approach, product size distribution generated at different levels of input energies is described by relating a number of parameters called 't n-family' parameters taken from the size distribution curves
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 ...

The mean size of the material passing the 0.15mm screen can be estimated assuming the bottom size is 1 micron. Particle Sizes Distribution Models. There is a common need to determine the amount of material in the feed at a given particle size. The desired particle size may not have been included in the original particle size analysis.
