Novel design modeling for vertical shaft impactors
The VSI components design has a significant impact on the device's efficiency. The crusher efficiency is greatly influenced by the contour of the centrifugal rotor and the ring armor [19]. In conventional VSI's, the centrifugal rotor contour is defined solely empirically; therefore, the trajectory of a particle's movement on a rotating ...
