Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).

Djordjevic et al. (2003) simulated the particle movement and calculated the velocity and energy distribution of collision in two types of impact crusher by applying the DEM technique: the vertical shaft crusher and the horizontal shaft mill. Experimental data of the hammer mill were used to verify the DEM simulation results.

The VSI used in both the simulations and the physical tests is a pilot-scale machine, model Barmac 3000 Duopactor, manufactured by ®. The crusher essentially consists of three parts: the feed hopper (Fig. 1), the rotor and the crushing chamber (Fig. 2, Fig. 3).The feed hopper, which is typically choke-fed, is responsible for …

1. Introduction. Impact crushers have become particularly useful in manufactured aggregates production because of the nature of the breakage mechanisms, which allow direct fragmentation of the particles without leaving residual stress in them (Wills and Finch, 2016).As such, material produced in a particular size range, which may …
