More recently data from Los Bronces SAG mill circuit has become available (Becerra and Amelunxen 2012) in which the SAG mill was operating in both SABC-B configuration where the crushed pebbles report to the ball mill feed chute and SABC-AB configuration in which the pebble crusher product is split between both SAG and ball mill

FULL PRE-CRUSH TO SAG MILLSTHE CASE FOR CHANGING THIS PRACTICE. c rushing of the SAG fee d and also diverted pebble crusher product to the ball mill. Cadia in New South .

Pebble Crushing Pebble crushers are commonly used in autogenous and semiautegous (AG/SAG) mills as they are a much more efficient user of power on this material thereby reducing the specific energy and increasing the throughput. As the recirculating pebbles are approximately 18 of the feed the installation of a pebble

The pebble crusher was reduced in size and the pebble bin capacity was increased to allow for a more consistent flow into the pebble crusher. Uncrushed pebbles were returned directly to the SAG mill bypassing the pebble crusher to further improve circuit efficiency.

the SAG mill and ball mill was 8658 kW which caused partial over-grinding. From experience in processing plants outside of China the power rating of the ball mill should be higher than that of the SAG mill 5 . The pebble crusher had an over-powered configuration. The installed power draw of 630 kW

As the pebble ports also allow steel balls to exit a steel removal system (such as a guard magnet Chapters 2 and 13 Chapter 2 Chapter 13) must be installed to prevent them from entering the crusher. (Because of this requirement closing a SAG mill with a crusher is not

controlled blasting practices and optimised primary crusher and grinding circuit conditions. For such Mine-to-Mill projects PTI s methodology is termed Process Integration Optimisation (PIO). Ahafo operate a SAG mill ball mill and pebble crusher (SABC) circuit that processes a range of

Oct 23 2019 · Robustness of the crusher Pebble crushing is the toughest of crushing applications so a crusher needs to be robust. Our Trio® TC series cone crusher is typically 40-50 heavier than similarly sized machines in the market and provides a superior level of protection against fatigue. When pebble crushing weight really does matter.

Pebble crushers also cause coarser AG product which might be an issue depending on your downstream process. But you can t use pebble crushers in SAG circuits because the iron ore and steel balls will confuse the crusher tramp steel protection. Either fully autogenous with or without pebble crusher or SAG without pebble crushing are valid.

The hypothesis put forward in this paper is that active control of the cone crusher s eccentric speed and closed side setting (CSS) can increase throughput and/or energy efficiency of the SAG circuit. To verify this hypothesis a dynamic model of a SAG mill-pebble crusher circuit was implemented.

acoustic device (SAG analyser). The mill is equipped with 70mm pebble ports and discharges onto a 30mm trommel screen. The 30mm trommel oversize is delivered onto a conveyor supplying pebbles to the secondary mill pebble feed bin. When this bin is full the pebbles will be routed to the pebble crushers via an overflow chute on the pebble bin.

SAG mills. Replacements are seldom done to SAG mills due to cost and also the constraints of other circuit equipment. Instead often additional production lines are added. Also if the bottleneck is the SAG mill adding a pebble crusher can provide a small production boost (typically 5 to 10 ).

Semi autogenous Grinding with Pebble Crusher. Given those circumstances it was proposed to study the installation of a pebble crusher in order to increase SAG plant capacity by improving the control of ultrafines production and simultaneously taking advantage of an operation at high power draw.

As the pebble ports also allow steel balls to exit a steel removal system (such as a guard magnet Chapters 2 and 13 Chapter 2 Chapter 13) must be installed to prevent them from entering the crusher. (Because of this requirement closing a SAG mill with a crusher is not

AG/SAG mills are normally used to grind run-offmine ore or primary crusher product. Feed size to the mill is limited to that size which can be practically conveyed and introduced into the mill. The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a ball mill pebble mill or

Pebble Crushing. The pebble crusher is considered part of the SAG mill for the purposes of this model. The displayed E peb value will always be zero but the displayed E asag will include the shell power of the SAG mill plus the usable power of the pebble crusher. Unlike other models there is no explicit benefit to E total efficiency due to

Grinding Classification Circuits. the oversize of screen after AG or SAG mill is called pebble and then the cone crusher in this circuit is called pebble crusher. SAG mill is Semi-Autogenous Mill which there is up to 15 ball inside and AG mill is Autogenous Mill which there is no ball inside the mill.

Oversize is screened and sent to a pebble crusher before being sent to the SAG mill. The undersize material is crushed in a single pass through the SAG mill. Key to the whole setup was a need to convey material 500-feet from the secondary crusher to a stacker which feeds the pebble bin ultimately providing fresh feed for the SAG mill.
