In the sand and gravel production line, because they are all stone crushing equipment, it is easy to generate noise pollution. Among them, crushers, sand making machines, screening machines, etc. are the main sources of noise pollution. Noise pollution brings many problems to the production of the majority of users. Comprehensive improvement is required.

Hydraulic cone crusher eccentric shaft assembly includes eccentric shaft, gear carrier, eccentric bushing and eccentric gear. Meanwhile, the eccentric shaft is installed in the body cavity of the lower frame. To prevent wear of the lower frame, the eccentric shaft is in contact with the bushing in the cavity.

Generally speaking, the dyeing gap between the eccentric shaft and the bushing is 1.5 mm, and the dyeing gap between the lower frame and the bushing is 0.22 mm. If it is not handled properly, the lower frame body will be worn out, so the eccentric assembly smooth operation is very important. Generally, the following factors affect the smooth operation of the hydraulic cone crusher eccentric assembly:

The single-cylinder hydraulic cone crusher is a stone crushing equipment with better performance than the traditional spring cone crusher. It is widely used in metallurgy, building materials, road construction, chemical industry and other fields. For granite, diabase, basalt, River pebble, limestone, dolomite, etc. have very good crushing effect. Can a single-cylinder hydraulic cone crusher crush granite?

Among the many crushers, some crushers can be seen everywhere, such as jaw crusher, impact crusher and so on.

But some crushers may be rare. Usually we call it a sand making machine, but it actually refers to a vertical shaft impact crusher, referred to as an impact sand making machine, which is an upgraded high-end crusher equipment.

Due to its high crushing rate, small grain size, small wear, good sealing, easy maintenance and other outstanding advantages, it is favored by the majority of users.
Before understanding the vertical impact crusher, let's briefly introduce its working principle.

The impact crusher has reliable performance and stable operation. The output of the impact crusher can reach 30-2000t/h. It is often used in stone production lines with a jaw crusher. The side length can be 100-500mm, and the compressive strength will not be stained. The medium and brittle materials of 350MPa are finely crushed and processed. It has the advantages of large crushing ratio, good material size after crushing, and diversified crushing specifications. This is due to its various adjustable and controlled output particle types and particle sizes. The method will be introduced in detail next.
