Starting as small as 13 feet 4 m in diameter on 330 HP and as large as 24 145 m in diameter on 3300 HP the 911MPE Semi amp Fully Autogenous Mills tumble crushed ore without iron or steel grinding media They are used when the crushed ore pieces are hard enough to perform all the grinding SAG mills tumble mainly ore but they use up to 15 volume of steel balls to assist grinding Semi
A semiautogenous mill is a piece of rotary equipment which is used to grind hard rock ore after being processed by crusher and before entering ball mill The mill liner provides a replaceable wearresistant surface for the mill grinds the materials in the mill and discharges the

Jun 01 2005 Having been in a few process plants with SAG mills amp they are inefficient as low as 1 since power costs are becoming a big issue there is lots of research being done try googling under SAG Mill efficiency technically I wouldnt consider them a crusher they are grinding mills and some mill people might take offence note that SAG mills are high compared to lengththis is so the
Ball mill design requires a Bond work index BWi for ball mills at the correct passing size SAG mill design requires an appropriate SAG test for example SPI Chapter 5 Flotation design needs a valid measure of kinetics for each sample including the maximum attainable recovery and rate constants for each mineral Chapter 12
Midsized pieces will get processed by each crusher before arriving at the SAG mill Other pieces well they just get stuck in the crusher The varying proportions of ROM ore sizes and their associated densities create challenges as the dynamic nature of the ore characteristics has a direct impact on the amount of time each piece of ore
In Figure 735 shows the SAG mill closed with a crusher recycle or pebble crusher In SAG mill operation the grinding rate passes through a minimum at a critical size Chapter 5 which represents material too large to be broken by the steel grinding media but has a low selfbreakage rate
The harder component of the SAG mill feed from the primary crusher that component with a higher bond work index will be over represented in the pebble circuit relative to the mill feed In many cases the low grade or barren gangue component of the feed will have these characteristics of higher hardness and lower breakability relative to the
If this is the case you could look at installing a magnet pebble crusher screen SAG feed size control and recirculating system back to your SAG feed then running a wider opening on your grates A project I worked on saw a 30 increase in SAG throughput ROI 90 days
