Several Measures of Ensuring Balance of Cone Crusher

During the material crushing process of cone crusher, the inertia moment on the crushing cone and the eccentric sleeve may increase the processional angle. However, since the processional angle is limited by the structure, it cannot be changed. When the cone crusher runs without materials in it, a counter-force will be produced that changes periodically with the rotation of the eccentric sleeve on the fixed principal axis and the ball bearing, thus causing harmful vibration of the equipment.

In order to eliminate the inertia force and the inertia moment produced by the crushing cone and the eccentric sleeve and ensure the normal operation of the equipment, it is necessary to ensure the balance of the cone crusher.

The inertia force and the inertia moment produced by the crushing cone and the eccentric sleeve of cone crusher have great influence on the balance of the equipment. Such inertia force and inertia moment produce on the machine frame which will produce periodic movable workload, thus causing great vibration of the equipment, which will cause damage on the crusher and influence the normal operation of the equipment. In order to solve these problems, several measures are listed in the following:

(1) Eliminate or reduce harmful vibration of the equipment caused by the inertia force and the inertia moment produced by the crushing cone and the eccentric sleeve and the additional moment of the principal axis as well.

(2) During the operational process of the equipment, maintain the eccentric sleeve in the correct position, otherwise the normal operation of the equipment will be influenced. The condition that the cone crusher can normally run is to ensure the axis of the crushing cone and the central line of the equipment intersects with the bearing center of the ball.

(3) No matter the cone crusher runs with materials in it or without materials in it, the workers should make sure that the eccentric sleeve presses on the fixed principal axis with the thick side in order to reduce the impact on the principal axis.
