Modelling SAG milling power and specific energy .

The test is a closed circuit, dry grindability test run in a small standard SAG mill using mill charge level control and air classification to give a minus 14 mesh product. The test is run continuously, similar to a small pilot plant, for a minimum of six hours and until a steady-state is achieved.

SAG MILL GRINDING DESIGN VERSUS GEOMETALLURGY

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed .

SAG Mill Grinding Circuit Design

SAG Mill Grinding Circuit Design

The designs of autogenous and semi-autogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills. Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described.

SAG Mill Optimization using Model Predictive Control

SAG Mill Optimization using Model Predictive Control

The use of modelling and simulation has become routine in the design and optimisation of AG and SAG mill circuits. One of the most widely used models for this purpose is the so-called " variable .

the work done by the AG/SAG mill (right graph). This figure is quite diagnostic of the problem discussed in this paper. It shows that the actual AG/SAG operating work index can be significantly biased, particularly for coarse transfer sizes. This result has led to misconceptions and terms such as "SAG mill inefficiency factor."
