1, vibration sieve is a vibration equipment with multi-vibration source, noise control can only in some kind of program to improve the environmental pollution, and the station uses a large number of vibrating screening machine, it is necessary to combine the plant insulation measures in order to achieve a more satisfactory effect.
2, As far as to meet the conditions of the bearing life, smaller size, higher stiffness of the bearing.
3, when using a metal sieve or a stainless steel slit sieve, as far as possible combine the screen frame together through a buffer rubber or plastic pad in order to reduce the noise generated, and reduce the impact of the metal member.
4. You should use more rubber and plastic components, practices proved that, in the screening of granular materials; the noise of rubber cooking sieve is lower 10 dB than the noise of the metal sieve.
5, The coil spring has a low natural frequency, the larger the static compression volume and carrying capacity can resistant high temperature, oil, stable performance, but it is easy to pass the high-frequency vibration and IF vibration. In order to reduce the noise, preferably sticking a layer of rubber in the spring wire can increase the resistance.
6, Rubber spring generates minimal noise when the work, to give more consideration in the design of the vibrating screen.
7, in the structure of the design of the sieve box, consideration should be given to the stiffness of the side plates; a suitable stiffness can reduce the vibration, thereby reducing the low-frequency noise waves.
