mineral processing mill noise level
Grinding Mill Control Metallurgist & Mineral Processing
We did not develop a specific control product, just made recommendations based on the mentioned findings. You may use the RMS noise level as an estimator of mineral load inside the mill, given that the speed is below the threshold for direct liner hitting and that you have multiple microphones to adapt to variable toe position.

Mill (grinding) Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Prolonged exposure to high levels of noise can result in permanent and irreversible damage to hearing. The only . effective preventative measure is to control noise exposure before hearing loss occurs.
Mechanical screening Wikipedia
Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling. [A method of separating solid particles according to size alone is called screening]
