I. Working Principle
When the machine is working, the motor drives the eccentric axial sleeve via spring coupling, transmission shaft and a couple of cone gear wheel. The axis of crushing cone is forced to swing by the eccentric axial sleeve and makes the opening of the upper mantle and the lower mantle changes in a certain range and the material is impacted and finally crushed.

II. Features
The advantages of the machine are simple operating, high efficiency, easy changed and low investment cost. The spring release system of the crusher acts an overload protection system that allows impurity like metals to pass through the crushing chamber without damaging the crusher, use dry oil and water, the two kinds of sealed formation. It made powder and lubricant separated, ensuring reliable performance.
