· There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact.

· Nitrogen and water limitation affected the resource-use efficiencies in maize crops through different mechanisms. Within each water regime, limited N reduced ɛ R by up to 40% in proportion to a reduction in SLN ( Fig. 7 a) which agrees with previous reports for maize under N stress ( Massignam et al., 2012 , Muchow and Davis, 1987 ).

· The maximum (limit) meshing angle of the crusher is determined by the friction coefficient between the crushed ore and the crushing working surface, which can be obtained by force analysis. The friction angle of the ore to the steel plate is generally 17 degrees, so the meshing angle should not be greater than 34 degrees.
