Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm). Single stage AG/SAG mills ...

For smaller plant in the 1980s, these ores were treated through a single-stage SAG mill grinding to 75 or 106 μm. This type of circuit is still straightforward in its design concept. High-competency ores or ores requiring a finer product size frequently require two stages of grinding and a number of design issues become important.• Mill ...

An illustration of the extremes in SAG circuit design is gained by comparing single-stage autogenous milling in a circuit closed with cyclones to a high ball-charge SAG circuit closed with screens. In many cases, the selected circuit configuration can be used as a guide to tailor the power input required for the application.

ABSTRACT The run of mine ore from Aghdarreh gold mine must be comminuted to achieve the desired degree of liberation of gold particles. Currently, comminution circuits include a single-stage crushing using a jaw crusher and a single-stage grinding using a Semi-Autogenous Grinding (SAG) mill in closed circuit with a hydrocyclone package.

After assessing the potential reliability difference between the 40 ft SAG mill and the equivalently powered 42 ft SAG mill, Newmont made the decision in 2010 to purchase a 42 ft SAG mill from and a 28 MW GMD from ABB. THE MILL Needless to say "reliability" is a key word at every stage of the project. Although mill structure failures ...
