Jan 01, 2016· For autogenous mills, like the dry Aerofall mills, MacPherson and Turner established that the power consumption was a function of mill diameter and length. For dry commercial AG mills they derived the power as (9.8) P M = 0.992 L D 2.8 ρ c where ρ c = bulk density of the mill charge (rock plus balls and water) (t/m 3 )
Macpherson Autogenous Grindability Test Mining Sgs. The mill power draw throughput and product size distribution are used to compute a specific energy input and the macpherson autogenous work index awi although the importance to achieve steadystate in a grinding test is widely accepted bond tests the macpherson test remains the only smallscale ...
power and Bond's equations an autogenous work index (AWi) for the sample was calculated. This measurement and calculation is valid at the product size produced. Subsequent work by Minnovex Technologies Inc. showed that the AWi value is a variable, depending on the product size produced in a semi-autogenous mill 3. MacPherson must have known ...
