Advantages of rubber spring: simple structure, low noise.

Rubber spring defects: give full consideration to the compressive strength of rubber spring, the design scheme can not make the bending stiffness down, bending stiffness is 1.5 to 2 times of the spiral spring, therefore, sent to the basic dynamic load, the service life is not as good as the spiral spring.

Helical spring advantage: can design the program is very soft, bending stiffness is small, sent to the basic dynamic load is much smaller than rubber spring.

Helical spring defect: complicated structure, easy to cause noise.

Therefore, large and medium-sized vibrating screen using coil spring is better, as far as possible to avoid vibrating screen load. Small and medium-sized screen can use rubber spring, because of the simple structure. In other words, the shaker load exceeds 15 tons using coil springs.

Vibration screen more than 25 tons, proposed in addition to the use of spiral spring, waveform spring can take into account the design scheme of vibration frame (secondary vibration), because the vibration frame can reasonably reduce the vibration screen load above 50%, the defect is the net weight of the vibration frame is very large, in order to achieve good vibration reduction actual effect, the net weight of the vibration frame must be 40% of the net weight of the vibration screen, Secondly, the overall aspect ratio of the vibrating screen will also be increased by 30%, and the overall reliability of the screen body is weak. Therefore, unless it is especially necessary to adopt the vibration reduction provisions, otherwise, it is not economic development.
