Hammer Mill Noise Control | eNoise Control

We suggest using acoustic steel sound panels to help abate the noise from a Hammer Mill. Either a sound wall or a full sound enclosure can be engineered around the high decibel Hammer Mill. This acoustic noise control approach can help lower the noise levels at the property line caused by this noisy grinder machine.

Noise and Impact Hammers

Measuring noise: Noise can be measured using a decibel meter. The name comes from Alexander Graham Bell and the unit of measurement is called- the bel. Usually the value in bels is multiplied by ten and the sound level is expressed in decibels (dB). More advanced devices are being used to determine the type of sound coming from impact pile hammers.

The Hammer Mill is used in the preparation of animal feeds and produces 93dB at 1.2m. An enclosure was constructed from a frame built from 50 x 50 mm wooden battens and clad in 19 mm plywood sheeting, glued and screwed together. The enclosure was designed to

Common Noise Levels

Common Noise Levels A“decibel” is the unit to measure the loudness of sound. Decibel levels for each item shown in the graph may vary. If you need to raise your voice to be heard an arm’s length away, the noise is probably loud enough to damage your hearing.

Mill (grinding)

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 ().
