Concrete crushers are powerful equipment to reduce concrete into smaller, more manageable pieces. Crusher buckets, for example, attachments to excavators and loaders, are used for crushing concrete on site. These units work by applying a force to the material more significant than its compressive strength, breaking it into smaller pieces.
Noise is measured as a "dose" that is calculated as a combination of the noise level and duration of the noise. The level is measured using the decibels scale, which is abbreviated as dB. This scale is a logarithmic scale meaning the noise level doubles with each 10 dB increase—at a level of 80 dB normal conversation is possible, …
Causes and Effects of Noise from Jaw Crushers. Jaw crushers generate significant noise levels due to the nature of their operations, including impact and grinding noises produced during the crushing process. The "crusher exhaust sound" and the "rock crusher sound" are common terminologies used to describe these noises.
