Vibrating screen is the main screening tool for coal preparation. Silo wall vibrator due to its own characteristics determine in the normal work must through the vibration to realize the screening, but vibration is the root causes of noise and high sound level, sound source many and complex.
1,All parts fastened on the shaker, especially the need for frequent replacement of the sieve, to avoid extra vibration due to the loosening of individual components produced;
2,Replaced punching steel sieve by small elastic modulus, anti-blocking devices low noise impact or rubber, polyurethane sieve sieve;
3, In the screen box side panels, feeding to the discharge port, the discharge port and rubber splice plate affixed inside the chassis, which can effectively suppress high frequency side vibration, reducing radiated noise;
4,Flexible webs gear instead of steel gear, namely in radiation board a rubber elastomer gear transmission torque warehouse wall vibrators, absorbing gear biting, gnawing the vibration caused;
5, With rubber alternative spring steel spring, in order to reduce the impact;
6, In vitro exciter install soft acoustic enclosures;
7, Damped between the inner and outer bearings, anti-blocking devices bearing rolling elements can be made into hollow rolling in the interior of the hollow body or the rolling elements added damping material, this can reduce the bearing vibration and reduce noise bearing.
