A noise control package for vibrating screens

01.03.2013· 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. The spring inserts and CLD treatments were selected due to their ease of

Application: Vibrating Screen

A Vibrating Screen manufacturer was experiencing difficulties with consistency of the bearing mounting in their shaker box assembly. At the same time they were looking for opportunities to save manufacturing cost and improve the overall performance of their machines. NSK engineers worked closely with this manufacturer and proposed that a complete bearing assembly be designed such that the

Structural Vibration as a Noise Source on Vibrating Screens

plant. Vibrating screens are a major noise problem in most coal preparation plants because screens are used extensively in plants, are usually located in high traffic areas, and can generate high noise levels [7]. The objective of this paper is to examine the noise radiated by horizontal vibrating screens below 1 kHz. vibrates,

Noise Control Measures : OSH Answers

Noise Control Measures. CLOSE ALL. How is noise made? Sound can be produced by vibration or as a result of aerodynamic systems. Vibration-induced noises are produced by: Mechanical shocks and friction between parts (e.g., hammering, pressing, running gears, bearings, cutting tools, chutes, hoppers, etc.) Out of balance moving parts (e.g., unbalanced rigid rotors) Vibration of large

Noise and Vibration Reduction of a Vibrating Screen

Workers in coal prep plants, where vibrating screens are significant noise sources, are often exposed to sound levels exceeding 90 dB(A). NIOSH, a major coal 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. Drive noise was

Assessing vibration: a technical guideline

vibration sources give rise to audible effects such as structure-borne noise and secondary rattling of building elements or contents. Individuals can detect building vibration values that are well below those that can cause any risk of damage to the building or its contents. The level of vibration

HSE Noise: Noise good practice Concrete and cement

Its use has the potential to eliminate the main source of noise (vibration). SCC should be discussed at visits to raise the profile and encourage innovation. European guidelines for self-compacting concrete [2.17MB] (See chapter 12 for information on pre-cast products) Blocks, tiles, slabs: Vibratory presses . Example noise levels*: 96-110dB (no noise reducing features) 84-93dB (outside press

High-frequency vibrating screens Wikipedia

The high frequency vibrating screens achieves a high efficiency of separation and differs from its counterparts since it breaks down the surface tension between particles. Also the high level of RPMs contributes to increasing the stratification of material so they separate at a much higher rate. Separation cannot take place without stratification. Furthermore, since the screen vibrates
