The primary crushing stage product is conveyed to a 67 kt capacity stockpile. Reclaimed ore is conveyed at 860 t/h to the grinding circuit, which includes one SAG mill, two pebble crushers and two ball mills. The grinding circuit is pumped to a desliming stage at a P 80 of 125 μm. The desliming circuit was not installed in the original processing circuit. However, reduced nickel mineral ...
Crushing and sizing stations | FL
Although we pride ourselves on large minerals processing plants, we also use our expertise to develop smaller flowsheets and equipment for all crushing and screening applications. Integrated with our gyratory crushers, jaw crushers, cone crushers, hammermills and low-speed sizers, we guarantee your entire process from the feed to the discharge end.

Basics of Grinding
grinding in that a number of workpieces can be ground simultaneously and in a continuous stream. The "infeed" mode is used for work with projecting heads that would prohibit "thru-feeding," the work is placed on the work-rest blade while one wheel is retracted and fed to an end stop. The wheel is then brought back, reducing the gap between the wheels, grinding the work. Surface grinding ...
HPGR simulation from piston-die tests with an …
The simulator combines Microsoft Excel (r) with a large database of models and a powerful solver to enable simulation of complex circuit flow sheets. Although it lacks the convenient circuit drawing capabilities of commercial mineral processing plant simulators, it has the important advantage of allowing rapid implementation of new or different models.

:: Innovations in Crushing Technology
But innovation in crushing has not been so rapid, and most of the developments reported in this area have been in control, simulation and optimisation of crushing circuits, rather than in new developments in the machines themselves. Indeed only two years ago, at Comminution '14, Tim Napier-Munn in his keynote lecture observed that in the 1970s Professor Klaus Schonert showed that the most ...

Crusher - Wikipedia
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
