Adopting Metal Helical Spring in Vibrating Screen Has Pros and Cons

Vibrating screen is an important machinery equipment used in industrial raw materials screening and coal processing and utilization, to classify ores, stone, coal, etc. Therefore, its technical level and using condition are directly related to the use of mineral resources and raw materials. Hongxing Machinery points out that isolation spring, the major part of the vibrating screen, has a great influence on the performance of the main engine.

At present, the circular vibrating screen and liner vibrating screen are the most widely used in China. The metal helical spring is mostly adopted as vibration isolation spring. People increasingly realize that, effective vibration isolation measures must be taken by selecting good vibration isolator in order to avoid the vibrating screen transmitting large dynamic load to the foundation, making the foundation and building vibrates dangerously, and to reduce harmful noise. The vibration isolation spring provides a elastic support for the vibrating body, to make the body produce elastic vibration, and reduce the dynamic load on the foundation and structural bracing frame.

The metal helical spring is one of the most widely used elastic device among vibration machinery, having the advantages of easy to manufacture, small internal friction, low energy consumption and so on. And it still has disadvantages such as large volume, easy to make noise, inconvenient to adjust its stiffness and small lateral stiffness which is liable to make the body swing transversely. The metal wire is easy to fatigue and break, causing a sudden accident and affecting production. Besides, the metal helical spring is a major source of noise pollution.
