VSI Series Vertical Shaft Impact Crusher

Large pieces of ore fall from the feeding hopper into the upper throwing tray in the upper crushing cavity, and the material is thrown to the inner wall of the cylinder by the centrifugal force of the throwing tray, and collides violently with the counter board installed on the inner wall. At the same time, the materials collide with each other, causing them to break or generate a large number of capillary cracks. Then after entering the conical rotor cavity, the material spirally falls in the conical space, and the crushed ore is further crushed by punching and extrusion. Due to the inclination between the conical rotor and the liner, the smaller materials will move downward, and the graded crushing from big to small can be realized automatically. When the material is hit by the hammer head in the conical rotor cavity, the high-speed running block material collides with the impact plate again, and the material flow collides with each other, so that the material is crushed by impact, collision, shearing and extrusion, and the crushing rate is improved. efficiency.
