The SAG Power Index test mill is 12" in diameter x 4" long and was chosen to be the same diameter as a Bond mill and to maintain a 3 to 1 diameter to length ratio. The mill runs at 70% critical speed and uses 15% by volume of steel, the maximum for commercial use in a SAG mill and a practical requirement for testing to avoid long grinding ...
The Bond BMWI has no correlation with the throughput or power requirements of a SAG Mill. Should be carried out on samples from each ore domain and in conjunction with a full JK Drop Weight Test for correlation purposes. The SMC Test requires significantly less sample than the JK Drop Weight Test or JK Rotary Breakage Test.
of fully autogenous grinding will be less and may require the use of steel in the SAG mill. In North America, designers have preferred to focus on large diameter, short SAG mills, diameter/length ratios in the range of to, with a transfer size to a ball mill in the range of 200 to 3000 microns.

Mill (grinding) Wikipedia. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge.
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill.
