vibrating screen reduction

Evaluation of Stiffeners for Reducing Noise from Horizontal Vibrating .

Sound levels around vibrating screens in coal preparation plants often exceed 90 dB(A). The National Institute for Occupational Safety and Health (NIOSH) is developing noise controls to reduce noise generated by horizontal vibrating screens. NIOSH researchers used finite element analysis (FEA) and a NIOSH written.
