Research of the Ejection Angle of Guiding Device in Vertical Shaft Impact Crusher Rotor

In this paper, a new rotor with two impact in the vertical shaft impact crusher is analyzed, an effect of the angle at the guide device thrown materials on the velocity that material reach the impact plate and rebound to a anvil in the crushing chamber are discussed. three mass ejection Angle are simulated by discrete element software EDEM, and the result shows that effect of two impact of new rotor on acceleration material is best when ejection angle is 25 °.
