In the inertial cone crusher, there is no rigid connection between the moving cone and the transmission mechanism, and the amplitude of the moving cone is not limited by the transmission system and can be changed. Its size depends on the balance between the material layer pressure resistance and the crushing force. When the crusher starts, the vibration frequency of the moving cone is small, the crushing force is small, the amplitude of the moving cone is smaller, so the starting moment is also smaller, and the crusher will not be damaged by starting with load. So, the inertial cone crusher can start and stop with load. Similarly, in the inertial cone crusher, the packed feed only increases the pressure resistance of the material layer, reduces the amplitude of the moving cone, and does not cause the crusher to “stun the car”.Loading feeder. Under the action of inertial force, the moving cone will be as close as possible to the fixed cone, thus breaking the material more finely. The maximum granularity of the product is only about 1 / 3 / 1 / 4 of the discharge gap. Since there is no rigid connection between the moving cone and the transmission mechanism, If a non-breakable object is mixed into the material, the moving cone will stop moving temporarily, and the exciter will continue to rotate around the cone shaft, which will never destroy the transmission system and the main engine.
Because the inertial cone crusher is started with load, compared with the no-load start of the eccentric cone crusher, the starting torque of the inertial cone crusher is larger, so the instantaneous current of the crusher is large. In order to ensure the crusher to start safely and smoothly, A large power motor is selected. In fact, the power consumed by the crusher is only about 60% of the rated power of the motor when it works normally. The rotary pendulum frequency of the moving cone of the inertial cone crusher varies from 750,2200 rpm to 2200r / min according to the different models. The oscillating frequency of the moving cone is much higher than that of the eccentric cone crusher. Therefore, in the process of crushing, the material is broken up to dozens of times in the crusher chamber of the inertial cone crusher.Which is much larger than the number of times the material is broken in the crusher chamber of the eccentric cone crusher. Moreover, compared with the eccentric cone crusher, the dynamic cone crusher has a variable amplitude of the moving cone, which is accompanied by more than 100 vibrations every week along the material layer. The crushing ratio of inertial cone crusher is much larger than that of eccentric cone crusher and can be adjusted in a wide range.
