How to choose the correct pebble crusher for your site

 · To sum up, the most important factors in selecting a pebble crusher are its ability to operate at tight settings and to withstand regular and significant tramp events. The smaller the crush size, the more rapidly the pebble load will be reduced, so we recommend using a heavy, robust crusher, such as the Trio® TC series, to achieve higher throughput rates in the milling circuit.

Riverstone Crusher

Recycle pebble crushing is widely deployed in autogenous grinding (AG) and semi-autogenous grinding (SAG) mill circuits. The application of pebble crushers can significantly boost circuit throughput by reducing critical size pebbles that potentially cause a bottle-neck in a primary grinding operation. Previous research shows that by controlling the cone crusher operational parameters, the ...

Pebble Crushing

 · Pebble Crushing. The Bagdad mill, built in 1977, was designed for a mill capacity of 36,300 tpd. An ABC (Autogenous Mill-Ball Mill-Crusher) grinding circuit was chosen. The original mill contained three completely independent grinding circuits, each containing one 9.75 m diameter by 3.96 m long fixed speed autogenous mill, one 4.72 m diameter by 6.

The crushing circuit is identical to the equivalent area in Phase 1, except for the addition of a pebble crusher in the pebble recycle circuit. As in Phase 1, The SAG mill slurry discharges through a trommel where the pebbles are screened and recycled to the SAG mill via conveyors, but in this phase, the addition of a pebble crusher in the recycle circuit will avoid build-up in the SAG mill.

Energy Curve Enhancement Blog 8: Including pumping …

 · Based on experience and the energy curve database, a typical primary crusher and the SAG mill can be assumed to be 1 km apart, consuming about 0.40 kWh/t in conveying power. Another 500 m of conveying can be assumed to be required for the pebble recycle, but since the flowrate is only about 10% of the feed, the contribution of the pebble recycle may be as low as 0.02 kWh/t.
