Spring cone crusher or Symons cone crusher is the key equipment to realize the energy saving technology, “more crushing less grinding”. Cone crusher is suitable for crushing raw materials in metallurgy, construction, road paving and silicate industry, and it can be used for crushing all kinds of ores and rocks with medium and over medium hardness. Cone crushers have such advantages of big crushing ratio, high efficiency, low energy consumption and even product granularity.

Spring cone crusher has the features of large capacity, low energy consumption, good product granularity, low failure rate, long service life, etc. But it also has the problem of vibration in its working process. On the basis of analyzing the working process of spring cone crusher, Henan Hongxing Mining Machinery Co., Ltd. will make a detailed analysis to its vibration.

When spring cone crusher is working, due to the effect of eccentric sleeve, the moving cone’s rotation axis and revolution axis make an angle. So, in turn, two cone surfaces approach to each other, and separate in turn. When approaching, crusher crushes materials; when leaving, materials discharge by gravity. By its principle of work, we can see that spring cone crusher adopts the crushing way that the eccentric compression is given priority to, so crusher vibration is inevitable. When crusher is in no-load running, it has obvious simple harmonic motion, and in the load running, especially when crushing lump ore, moving cone’s rotating speed in a short time is reduced, the vibration at that time has a large instantaneous impact component.

Inertia force and inertia moment have periodic change in direction, which determines the vibration form of spring cone crusher is a horizontal vibration, vertical vibration and swing. Due to the material layer’s uneven distribution in crushing cavity and material particle size is differ, so crushing cone rolls along the material layer with a strong shock and vibration, which has the additional vibration on the crusher.
