Modelling of output and power consumption in vertical shaft impact
Abstract. The vertical shaft impact (VSI) crusher is a commonly-used machine in aggregate production. A comprehensive understanding of the physical phenomena that influence the power consumption and the particle output of the device are essential to enable development of protocols that minimize energy consumption during crushing. The best crushing is observed under direct impact when the particle velocity vector and the impact plate surface make an angle of 90°. To estimate the influence of crusher design and particle properties on the crusher performance, the mathematical model has been constructed for motion of a particle in working area of Metallurgical Slag Disintegration in Centrifugal Impact

The crushing chamber is the core component of a cone crusher, consisting of mantle and concave parts. Reducing the impact of crushing chamber wear on the performance of cone crushers and the quality of crushed products while extending the service life of the mantle and concave has become a significant research challenge. The The evaluation of the impact crusher’s performance was based on the recorded energy dissipation in each of the iteration events in the simulated period.
