One of the first approaches to the development of a grinding process monitoring system based on audible sound sensors is presented in the paper. Electroplated diamond tools (abrasive D64 and D107) were used in a modified single-disc lapping machine configuration for flat grinding of ceramics (Al2O3). The main aim of the machine modification was to reduce the vertical vibration in order to ...

How to Reduce the Noise of Grinding Mill Source: clirika Posted: As we all know, there will have lots of problems when we are using the grinding mill, and the problem is not only include question of operation, but also include the question of the equipment itself, this is the reason of why we should maintain the grinding mill every ...
The grinder is old and generates a lot of noise. More than 110db while grinding. We did build a sound enclosure around it to reduce the noise but did not do much difference. We reduced around 10 -15 dB. According to regualtion it should be 85dB. We used a Filled EVA barrier with foam and a filled EVA sheet.
1. Enclose the machine that is creating the noise. This is becoming increasingly common and our recent work for Ardagh Group in Deeside saw the team create bespoke acoustic enclosures for each of the individual machines to reduce the noise they emit to below the legally required lower exposure level of 80db.
The grinding test was performed at the Saint-Gobain Higgins Grinding Technology Center near Boston, Massachusetts. The test machine was an Elb creep-feed/surface grinder. The operation was slot grinding using an 8-inch-diameter, ½-inch-wide conventional abrasive wheel. The material ground was 4340 hardened steel.
Common equipment applications include compressors, generators, blowers, hydraulic pumps, industrial fans, vibratory bowl feeders, routers, print presses, plastic grinders, and many other noise offenders. Let us design an enclosure to meet your noise reduction goals.

Silentium has developed unique Active Noise Control (ANC) technology and an entire disruptive sound management solution, incorporating proprietary, innovative algorithms that adaptively follow the changes in the noise spectrum, achieving extraordinary results of almost 10dB (A) noise reduction. The result is a small, low-cost highly effective ...
Machine shops are workplaces that are filled with tools and machinery that produce high sound pressure levels ranging from 80 to 110 decibels, according to Noise Buster. Understanding exposure levels in these environments helps you understand the importance of proper protection that can protect you from permanent hearing damage.
Where it is reasonably practicable to do so, employers must reduce noise exposure by means other than the provision of hearing protection. Common noise reduction measures. design changes to a process, component or machine; segregating noisy machines from …
A machine shop consists of multiple apparatus with metal grinding against metal countless ways, over and over again, all over the workspace. The din all that action makes is almost on a par with road construction or airport runway noise. What can you do? No matter how much you lubricate those machines, they are going to make noise.

The operation was slot grinding using an 8-inch-diameter, ½-inch-wide conventional abrasive wheel. The material ground was 4340 hardened steel.
For example, noise-reducing saw blades can cut noise levels in half when cutting masonry blocks. Old equipment can be made quieter by simple modifications, such as adding new mufflers or sound absorbing materials. Old equipment is also much quieter when it is well maintained. Simple maintenance can reduce noise levels by as much as 50%.

Engineering noise control 249 Figure 10.2. Sound sources should not be placed near corners (ASF, 1977) include rejection of the proposed design. The first step for new installations is to determine the noise criteria for sensitive locations
All rotating machines generate vibration during operation. Excessive vibration can shorten the service life and even cause damage to the machine.When the machine is running at high speeds, sometimes we can clearly feel the vibration, and it is accompanied by harsh noise. The spindle will heat up in a short time.

The typical noise reduction achieved by lining the roof of a factory with a sound absorbing material is shown in Fig. 2 as a function of average machine spacing. With densely packed machinery in a factory, the reduction in a factory, the reduction in sound level due to the absorption is very small.
When employees are subjected to sound exceeding those listed in Table G-16, feasible administrative or engineering controls shall be utilized. If such controls fail to reduce sound levels within the levels of Table G-16, personal protective equipment shall be provided and used to reduce sound levels to within the levels of the table. 1910.95(b)(2)
J & E Hofmann Engineering is a large manufacturer and repairer of mining equipment, specialising in metal gear cutting. Various noise sources are associated with the process. Layout The section of the workshop where all the grinding and welding takes place was designated as a noisy area.
CNC machines. We were able to reduce CNC machine noise by 9 - 10 dBA using a simple noise suppression treatment. Coater. The noise from paper coater machines was reduced by 10 - 14 dBA using low cost acoustic engineering treatment. Compressed air. Numerous compressed air noise problems have been solved successfully.
Achieving these goals requires a combination of machine enclosures, general absorptive acoustic treatment and possibly hearing protection. Featured Applications: AECOM Industrial Plant - Acoustical blanket wall using AudioSeal® blankets to block noise from equipment, reducing the noise for the employees in plant.
