How to deal with the abnormal vibration of the multi-cylinder cone crusher

The abnormal vibration of the multi-cylinder hydraulic cone crusher is very harmful to the equipment, and the production capacity and efficiency will be *ly reduced. Such as adjusting ring bounce, frame swing, etc.

 Multi-cylinder hydraulic cone crusher requires horizontal vibration within +2mm and vertical vibration within +1mm. Failure of the mounting surface to meet the requirements will cause abnormal vibrations such as rack swing. There are two installation surfaces, one is the foundation installation surface, that is, the installation plane of the vibration damping block; the other is the installation plane of the rack. The flatness of the two installation planes should be within 2mm, and the steel plate can be used to adjust the ones that do not meet the requirements.

The bounce of the adjustment ring of the multi-cylinder hydraulic cone crusher is an obvious manifestation of overloading. When the crusher is overloaded, the adjusting ring moves upward to increase the discharge opening, accelerate the material discharge in the crushing chamber, and reduce the load of the crusher. After the load of the crusher is reduced, the adjusting ring will move down and return to the original position. When the crusher continues to be overloaded, the adjustment ring will continuously reciprocate up and down. The intuitive * is the beating of the adjustment ring.

The main reasons for the overload of the multi-cylinder hydraulic cone crusher are:
1,The feedstock contains non-broken materials, such as metal, wood, rubber or plastic. Multi-cylinder cone crusher is strictly prohibited to pass iron. The iron passing release device is a kind of protection for the crusher, and it cannot be understood as the crusher has iron passing capacity. The material must pass through the iron remover and metal detector before entering the crusher.

2,Non-centered feeding is concentrated on one side to form single-sided crushing. The multi-cylinder hydraulic cone crusher requires that the feeding material must be centered, that is, the material fed into the crusher must fall vertically on the distribution plate. Achieving full feeding can ensure that the feeding is evenly distributed around the crushing cavity. The full feeding is a necessary condition for the operation of the multi-cylinder cone crusher.

3, Feeding segregation, large materials occupy one side and fine materials occupy the other side. Feeding segregation will not only cause machine vibration, but also cause uneven force on the crushing motor cone, which will seriously affect the service life of the crusher.

4, There are too many fine materials in the feed, and the requirement for materials smaller than the discharge port of the crusher in the feed is less than 10%. Too much fine materials will cause the crushing cavity of the crusher to be filled with fine materials and drive during extrusion. The power is *ly increased, which directly causes the crusher to overload.

5, The feed material contains too much water, and the water content of the crushed material should be controlled within 5%.
