The ROM ore is fed onto the vibrating grizzly feeder, where the screen oversize coarser than 115 mm is directed to the jaw crusher, which crushes the screen oversize to a P80 of approximately 150 mm. The crushed ore reports to the surge bin feed conveyor which also receives the vibrating screen undersize.

 · 69 ROLL CRUSHERS METHOD OF FEEDING. The feed should be spread evenly. Rolls can be fed "Free" or "Choked". Choke feeding is more efficient – higher crushing capacity. reduced wear of rolls ( ore onore grinding occurs). CAPACITY OF ROLL CRUSHER. C ( tonnes / hr ) = 60 V L S ρ V = Peripheral speed ( m/mt). L = Width of the rolls ( m).

the crushing efficiency. => Choke feed level for an HP cone crusher is 300 mm or more above the feed plate. • The feed must be distributed evenly 360º around the crushing chamber. Uneven feed distribution may cause power and force cycles through each gyration cycle. Evenly distributed feed will result in a more steady power and crushing force.
