Why does circular vibration screen choose rubber spring?

2. Compared with metal product, the rubber spring’s elasticity coefficient and hardness can be changed in larger range. Through changing the rubber hardness, its stiffness can be changed, which means the rubber spring’s rigidity range is wide, or even different rigidity can be chosen with the same shape rubber spring.

5. The resistance of rubber spring’s noise transmission is much larger than the metal spring’s. So its sound-proofing effect is better, which means the working noise is small.
