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.

 — Hardness levels can range from that of concrete at 7000 psi to 50,000 psi for ores or other hard materials. The harder the material, the longer it may take to crush. In addition to production times the degree of hardness will influence the specific crusher for the operation. JAW CRUSHERS
