Laboratory testing demonstrates that this noise control suite reduces the A-weighted sound power level of the vibrating screen by 6 dB. To provide a comparison to laboratory results and prove durability, field testing of two noise controls was performed on a vibrating screen in a working coal preparation plant.
A circle-throw vibrating machine is a screening machine employed in processes involving particle separation. In particle processes screening refers to separation of larger from smaller particles in a given feed, using only the materials' physical properties.
Acoustical Surfaces Inc. has been providing acoustical solutions to soundproofing, noise control, acoustical and vibration problems for over 35 years. With over 400 specialty soundproofing and noise control products and materials, ASI has a solution for almost any noise problem.
Workers in coal-preparation plants, where vibrating screens are significant noise sources, are often exposed to sound levels exceeding 90 dB(A).
Two-axle vibrating screen is a widely used piece of equipment However, its noise is high and very difficult to control In order to design low-noise vibrating screen, the noise sources of the vibrating screen and its noise characteristics have been analyzed The low noise material and machine .
High frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to approximately 200μm in size, and are applicable to both perfectly wetted and dried feed.
Reduce noise levels, control airborne noise and structure-borne vibration within manufacturing facilities through the use of curtains, barriers, baffles and damping materials
Control of risks and exposure • Aim for noise control by technical and organisational means • Wherever there are risks from noise employers should: – look for alternative processes, equipment, methods for quieter working or reduced exposure times. – keep up with good practice for noise control in their
Soft dB stands out in the acoustic measurement and control of industrial noise and vibration problems. We use state-of-the-art equipment for acoustic imaging, beamforming as well as acoustic sensors to measure acoustic intensity.
Normally the noise control program will be started using as a basis A-weighted immission or noise exposure levels for which the standard ISO 11690-1 recommends target values and the principles of noise control planning.
The hierarchy of noise control includes elimination or substitution of noise sources, collective control measures through engineering and work organisation, and personal protective equipment. There are several ways in which noise can be controlled, which can vary from one workplace to another.
Noise and vibration reduction of a vibrating screen D.S. Yantek, P. Jurovcik and E.R. ... company and a vibrating-screen manufacturer conducted a cooperative study of vibrating-screen noise. Rubber isolators reduced sound levels by 1 dB. Urethane screen panels did not reduce sound levels in this case.

Over 50 years of success solving noise & vibration control problems • Largest Selection of • Standard Products • Custom Engineered Products and Systems
A common technique to control noise from a source to a receiver - in this case, the operator's ear - is to block the noise from the source with an acoustic enclosure. NIOSH has developed such an enclosure to surround the mechanism housings, thereby reducing the noise that reaches the operator's ear.
