Simulation of particle flows and breakage in crushers using DEM: .
WEBApr 1, 2015 · Vertical Impact Crusher. In the hammer mill, a high speed impactor generates collisions with slowly moving feed. An alternative arrangement is to generate streams of high speed feed particles and have them collide with stationary surfaces. One such class of crusher is called a vertical shaft impactor (VSI). Fig. 16 shows a CAD .
