Vibrating screen compression spring
Vibrating screen springs is a very important part of the vibrating screen, their main role is to provide the necessary elastic and vibration support for the vibrating screen. When the vibrating screen starts to work, the exciter will produce a periodic vibration force, so that the screen box and screen will vibrate. In this process, the compression spring plays a key role. Through their elasticity and deformation, they provide the necessary support and buffer for the screen box and screen, making the screening process more stable and efficient.
The performance of the vibrating screen compression spring directly affects the screening effect and service life of the vibrating screen. If the elasticity of the spring is insufficient or the deformation is too large, it will cause the vibration of the screen box and screen to be unstable, and may even damage the equipment. Therefore, the selection of a suitable compression spring is crucial to the normal operation of the shaker.

Spring test standard
appearance test
Through visual inspection or magnifying glass observation, check whether the appearance of the spring is intact and whether there are obvious defects, such as cracks, rust, deformation and other problems. If the requirements are more strict, we can also use flaw detection equipment for testing.
Measurement length and diameter
The measurement of length and diameter is an important part of the performance test of compression springs. Use appropriate tools to accurately measure the length and diameter of the spring to ensure that it meets the design requirements.
hardness test
For the coil spring for vibrating screen, its hardness is also an important performance parameter.
Other performance tests
According to specific needs, other performance tests can also be carried out on the spring for vibrating screen, such as fatigue life test, durability test, etc.

| 2 | Spring ends | Flat area≥2/3 |
| Plane roughness≤12.5 | ||
| Thinnest thickness≥1/8d(Wire diameter) | ||
| 3 | Hardness | 44-52HRC |
| 4 | Surface | The surface should be smooth, without visible defects |
| 5 | Metallographic | According to material standard |
| 6 | Perpendicularity of spring axis line and end face | Spring height≤250mm error of perpendicularity≤3mm |

Maintenance
The vibrating screen compression spring needs regular maintenance and maintenance during use to ensure its good working condition. This includes checking the deformation and wear of the spring, cleaning the dirt and impurities on the surface of the spring, and adjusting the preload of the spring. If the spring is found to have serious problems or damage, it should be replaced in time to ensure the normal operation of the shaker.
