A fundamental model of an industrial-scale jaw crusher

Jaw crushers have been modelled previously; in 1953, Gauldie conducted a performance study of the jaw crusher, including a capacity model that handles varying speeds and closed side setting (CSS) (Gauldie, 1953).The kinematics of the single-toggle crusher has been modelled by Oduori et al. (2015).An energy efficiency study was performed by Legendre and …
