CRUSHERS

CONE CRUSHERS This type of cone crusher is suitable for high-capacity secondary crushing applications where a larger feed opening is required. Crusher has a larger intake capability and a high capacity in relation to its size. Mainshaft is hydraulicallya robust

Why it pays off to invest in multi-stage crushing process

 · Let''s start with the primary jaw crusher, the C120. For a two-stage crushing plant with the feed material properties in this example, it is not possible to squeeze the CSS any tighter than 100 mm as the power limit is the limiting factor.

Cost-effective and trouble-free secondary crushing with GP …

 · The big feed opening of the GP Secondary is indirectly benefitting the primary crusher, a jaw crusher in this example, which can be operated with a more open closed side setting (CSS). A larger CSS gives the jaw dies significantly longer lifetime, visibly smoother feed material flow and higher productivity for the plant.
