Movement state of ore material in jaw crusher

[yoyocrusher]

During the movement of the ore crusher, the speed of the spindle rotation of the equipment is sufficiently high. Under such conditions, the moving cone surface will generate a local acceleration that can exceed the acceleration of gravity. At this moment, the movement The ore particles will be in a free fall state. At a certain time, the particles will be able to catch up with the moving cone. If the moving cone is still away from the fixed cone, the particles will continue to slide in the subsequent motion.

When the speed of the main shaft of the crusher is relatively high, the ore particles in the crushing process will be completely in a free-fall state, until the swing angle of the moving cone reaches a certain angle, the particles will hit the moving cone on. Therefore, the state of motion in this case is different from the state of motion of the particles described above.

The effective stroke of the material in the crushing cavity is also different according to the speed of the different spindles in the . The effective stroke may be equal to or less than the nominal nominal stroke. According to the dynamic principle of object movement, we have also carefully studied and analyzed the effective stroke in each state of movement to help the crushing equipment to reasonably crush the material.

Therefore, the structure of the crushing cavity of the crusher and the rotation speed of the main shaft jointly determine the form of motion experienced by the ore particles during the crushing process. In simple terms, for a given rotation speed, at least one of these three states of motion will occur depending on the position of the particles in the crushing cavity. Therefore, it can be inferred that: when the rotation speed is relatively low, the geometry of the crushing cavity determines the particle movement; when the rotation speed is relatively high, the kinetic parameters of the crusher determine the ore particles in the crusher.
