Can reduce noise 12 ~ 15dB (A). 3. The choice of the lining board In the selection of the lining plate, replacing the manganese steel lining plate with the rubber lining plate can reduce the impact noise of the cylinder. This noise reduction method is very practical, but the life of the rubber lining plate has always been discussed. 4.
A brief introduction of 3 common mill types: Ball Mills a horizontal rotating cylinder containing a charge of steel balls. The balls tumble as the mill turns and material caught between the balls is ground to powder. TableRoller Mills a horizontal table rotates with springloaded rollers mounted above.

766 Selva Kumar A and Abdul Zubair H., 2017/Advances in Natural and Applied Sciences. 11(7) May 2017, Pages: 763772 • Headaches and migraines: The most common shortterm effect of noise pollution is a headache or migraine. The constant annoyance of noises can often lead to painful headaches, which can make focusing difficult for some people.
What is the ball mill noise? Ball mill noise is mainly mechanical noise caused by the collision between the metal ball in the drum and the cylinder wall liner and the processed material. The intensity of the ball mill noise is related to the diameter and speed of the ball mill, as well as the nature and blockiness of the material.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
Walks the walk, talks the torque.

Numerical modelling of the pilot mill with a coupled discrete element modelling (DEM) and smoothed particle hydrodynamics (SPH) was also performed to compare the acoustic beamforming results. It was indicated that level of the acoustic noise generated during mill operation is more associated with steel ball filling rate rather than the mill speed.
