HPGR vs SAG - Grinding & Classification Circuits ...

May be an easiest way to show when HPGRs are needed in a circuit is to look at those projects where a SAG mill circuit didn't reach design capacity. If I remember well ALL of the SAG circuits dealing with competent ores have been forced to add either pebble crushers or secondary crushers to reach design capacity. This situation has transformed some SAG mills into an "unusual" hybrid mill ...

Many of the early autogenous grinding installations in the United States and Canada were used to grind iron ores. Generally the results showed the final product contained less fines (the screen analysis as plotted on log-log paper had a steeper slope) than the products from circuits using more conventional media. This led to the statement that autogenous grinding produces less extreme fines ...
