### Cone Crusher - an overview | ScienceDirect Topics

After the primary crushing, which is normally performed using jaw crushers (Fong et al., 2004), it is preferable to adopt a secondary crushing stage (with cone crushers or impact crushers) (CCANZ, 2011) to further reduce the size of the CDW, producing more regularly shaped particles (Barbudo et al., 2012; Ferreira et al., 2011; Fonseca et al ...

### Gyratory Crusher - an overview | ScienceDirect Topics

Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.
