    • Noise controls for vibrating screen mechanisms

    2012-8-30  For the Conn-Weld screen tested at NIOSH, two vibration mechanisms are mounted to a steel beam that spans the width of the screen. These vibration mechanisms, which use rotating eccentric shafts to generate vibration, are belt-driven using an electric motor. This screen is designed in such a way that it vibrates on roughly a 45 ° angle.
