Controlling ball mill noise with acoustic blankets:

The purpose of wrapping ball mills with thermal/acoustic blankets is twofold: (1) to maintain the desired temperature inside the mill and (2) to reduce the sound emanating from the mill. This field case study focuses solely on the latter, evaluating and documenting the sound level reduction attributed to the installation of the blankets and its potential to reduce the noise dose experienced by

Size reduction of material using ball mill -

At low speeds the ball rolled over each other and attrition takes place. 1,2 At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that break contact with the wall and fall to the bottom to be picked up. In this manner impact stress will also be induced and the size reduction made effective.

Reduction of noise during milling operations -

From rotational speeds of 6000–12,000 rpm, the noise emission of the surface mill (diameter 125 mm) increased steadily reaching 98 dBA at 12,000 rpm, whereas the solid end mill reached a value of 82 dBA. The characteristic frequencies of the machine and of the spindle rotation at 12,000 rpm disappeared and a broadband noise appeared. This behaviour is typical for aerodynamic noises

Ball Mill: Operating principles, components, Uses

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. The large balls tend to break down the coarse feed
