Cone Crusher Noise Produce And Reduction

With the rapid development of economy in the modern society, the consumption of metallurgy and construction material is getting higher and higher, so does the raw materials that need to be crushed. Spring cone crusher, as very important crushing equipment, plays very important role since created. But in the operation process of cone crusher, there is large noise produced, which affects the normal working of operators and the running of crusher. In this article, we mainly introduce the produce reason and reduction of noise in spring cone crusher.

Two Important Matching Clearances In Spring Cone Crusher

Matching clearance between the principal axis and taper bushing and matching clearance between eccentric bushing and frame bushing has great effect on the safety operation and produce of noise in spring cone crusher.

Matching Clearance Between Principle Axis And Taper Bushing

Unlike the usual matching between sleeve bearing and bushing, the matching clearance between principle axis and taper bushing is cone-shaped and the upper clearance is smaller than the lower clearance. Besides, the volume is much larger than the sleeve bearing. On the one hand, the large matching clearance between principle axis and taper bushing is to ensure there is enough lubricating oil goes through the clearance, which can ensure the lubrication of principle axis and taper bushing but also bring some heat away; on the other hand, the large clearance is to meet the requirements about adjusting the spring cone crusher.

In order to make sure that there is certain adjusting range of spring cone crusher, the matching clearance between principle axis and taper bushing must be large. And the size of the upper and lower clearance is very important. If the size is too large, the spring cone crusher will work off normal and produce loud noise. If the size is too small, there will be much heat produced, leading to the lock of bearings. So in the installation or maintenance of spring cone crusher, operators should adjust the matching clearance to required size according to specifications or interrelated data.

Matching Clearance Between Eccentric Shaft And Frame Bushing

The clearance here features large size, which is not only used to make sure enough lubricating oil goes through the clearance, but also to bring the heat away. But if the clearance is too large, it will cause additional impact load to spring cone crusher and produce loud noise. If the clearance is too small, there will be much heat produced. So operators should check the damage condition of eccentric bushing and frame bushing, making sure the clearance reaches to requirement.
