The rubber spring is an important part of the vibrating screen, which can be used for shock absorption when the vibrating screen is working, so as to better increase the service life of the vibrating screen. The rubber spring can be made into products of various shapes and sizes. Its compact layout enables efficient use of space.

There is a device on the vibrating screen, which can slow down the large impact force of the vibrating screen when it is running, and is used for shock absorption and buffering. It is also very useful in the production line with large loads, and uses greater elasticity to control the movement of the vibrating screen. Springs play a huge role in vibrating screens due to their task of reducing gravity and bouncing.

The vibration damping springs usually used on vibrating screens are steel wire compression springs, rubber springs, composite springs and other three.

We need to accurately calculate the vibrating screen spring to make it reach the ideal operating state, so that the screening efficiency and effect can be reliably guaranteed. When designing the spring, it is also necessary to ensure that the static deformation of the spring is greater than the amplitude and the height of the limit device, otherwise, the body will be too large in amplitude, and the body will be separated from the spring instantaneously. The user can adjust the amplitude by controlling the eccentric weight.

  M 

In the formula, Z-frequency ratio, Z= (usually Z=3~5)

M —– vibration mass, kg;

—–Natural frequency, = =

The working frequency is also determined by the working conditions and process conditions like the amplitude, so the design of the rubber spring is the calculation of the spring stiffness and natural frequency.
