Assessing the energy efficiency of a jaw crusher
The Rose and English jaw crusher model equations were taken from the work of Gupta and Yang [4]. For a jaw crusher the reduction ratio (R) is defined with gape (G) as: (A.1) R = G L min [−] Therefore the close opening set (L min) for a jaw crusher can be written as: (A.1) L min = G R [m]
