A Method of C alculating Autogenous/ Semi-Autogenous
griding/semi-autogenous grinding (AG/SAG), mill speci c energy is now calculated by various fi empirical formulae and pilot testing carried out in small laboratory mills. Barratt (1989) described a method using Bond Indices than adding a single factor of 1.25 to arrive at the AG/SAG specifi c energy. In 1991 the Canadians developed the SAGPower Index (SPI), test using 2 kg of material in a

Mill (grinding) Wikipedia
Autogenous mill. Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill. Also known as ROM or "Run Of Mine

Grinding Mill an overview ScienceDirect Topics
In this situation the mills are often located at right angles. Alternatively, a transfer hopper can be used. This decision is usually based on the difference in cost and operability of each option. • Transfer size from the SAG to the ball mill. Transfer size prediction is somewhat uncertain but has an important impact on the balance of power between the two stages of the milling circuit. For

The 36 ft. diameter semi-autogenous grinding (SAG) mill pictured to the right smashes up to 55,000 tons of granite to copper and gold production- raw material size reduction is a requirement and grinding mills, the final stage in this process, are the most expensive component to operate. Improvements in SAG mill operation offers the greatest potential for cost savings.

Rod mills, how they function Mine Engineer.Com
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of
