Impact of Relative Motion of Crushing Cone on Crusher

For the traditional cone crusher, the crusher machine only can be started and stopped when there are no materials in the crushing cavity. If the machine is stopped in the load state, we must thoroughly clean the crushing cavity before restarting the crushing machine. Starting crusher machine with load is absolutely prohibited. In the conventional crusher machine, the connection between the crushing cone and the motor is rigid. In the operation process of the crusher machine, the swinging stroke of the crushing cone keeps unchanged because of the limits of the eccentric sleeves. Therefore, if you start the crusher machine when there are materials in the crushing cavity, the starting torque is required large, which will cause serious damage to the crusher and motor. Too many materials into the crushing cavity will cause the blocking problems of the crusher machine. Therefore, you should install the feeding machine for uniform feeding operations. When non-crushing materials enter the crushing cavity, the crusher machine will be seriously damaged. As a result, the traditional crusher machine needs the overload protection device, which will bring very high costs for the whole crusher machine.
The crusher allows to starting and stopping with load. Since flexible connection is used between the crushing cone and the motor of the crusher, the amplitude of the crushing cone is not subject to the limitations of the transmission system. When the crusher machine starts, the oscillating frequency of the crushing cone is small, the crushing force is also small and the swing angle of the crushing cone is smaller, so the starting torque is also small. As a result, start with a load will not damage the crusher machine. When there are no materials in the crushing cavity, in the running process of the crusher, the crushing cone rolls without gap along the inner surface of the fixed cone, which will cause the mutual attrition between the crushing cone and the fixed cone. This situation should not occur. Therefore, the inertia cone crusher must start with. Staring machine without load is not allowed.
