  • Vibratory screen having noise level reduction by isolation
    Patent number: 4180458
    Abstract: A relatively quiet vibrating screen has a rotatable eccentric mass drive supported on the screen body by isolator mounts which transmit vibratory forces at shaker frequency unrestrained to the screen body and attenuate forces at higher harmonics of shaker frequency that would otherwise excite wall panels of the screen body into resonance, thereby reducing the noise level of the screen.
