Cone crushers are fed with pre-screened material from the primary crusher (usually a jaw crusher or primary gyratory), and the secondary crusher should always, if possible, have a scalped feed. Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher.

Depending on hardness, crushability and abrasiveness, wear costs – related solely to the jaw crusher – are significantly lower than with impact and cone crushers. Cone crushers Cone crushers are the choice for use in medium-hard to hard and abrasive natural stone as well as for raw material preparation in mining applications.
