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.
Choosing a rock crusher hammer is made easier by the filters and search engine at Alibaba's catalog.

Hammer crusher is mainly used to crush material by impact. The crushing process is roughly like this. The material enters the crusher and is broken by the impact of a high-speed rotary hammer. The broken material obtains kinetic energy from the hammerhead, and thus rushes towards the baffles and screen bars at high speeds.
The noise intensity was measured at three area of the plants ; raw mill, cement mill, and sillo raw mix. There were 23 measuring points where considered as hazardous potential …
