The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.
Hongxing rod grinder is especially suitable for crushing river gravel to make sand. It's a kind of effective and energy saving rod grinding machine.
Vibratory feeder in the production line can transport the material with the shape of massive and particles smoothly to the feeding device in a stable time.
ABC closedcircuit, Autogenous-Ball-Mill-Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding …
If you feel there is a need to install pre-crushing for agreen field grinding circuit, it suggests you are SAG mill limited (because of ore hardness), in which case an HPGR/Ball Mill circuitshould be considered.
Economics changed and a review of thecircuitperformance including modelling and simulation resulted in thecircuitbeing converted tosingle-stage SAG, with theball millbeing idled at the lower tonnage.
SAG millis usually used to grind large pieces into small pieces, especially for the pre-processing ofgrinding circuits, thus also known as primary stage grinding machine. Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel.
ASAG Milltrommel screen lets you control the true discharge size of yourSAG millor the transfer size to the downstreamBall Mill circuit. A well sized trommel should not let rocks pass to theBall Millif they are to be more than say 5/8″ or 16mm In the image case below, strangely enough, Metso is themillshell liner and discharge grate manufacturer.

SAGmilling extends itself to many applications due to the range ofmillsizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rodmilland some or all of the work done by aball mill.SAG millsare also an optimum solution for wet grinding since crushing and screening in these ...
AG/SAG millscan accomplish the same size reduction work as two or three stages of crushing and screening, a rodmill, and some or all of the work of aball mill. Because of the range ofmillsizes available, AG/SAGmilling can often be accomplished with fewer lines than in a conventional rodmill/ball mill circuit. A diagram of types of AG/SAG...
