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.
How To Reduce Or Control The Ball Mill Noise. The mill decreases the mill noise intensity grows inversely as shown in figure 7 this effect is the basis of the electric earpatented by hardinge to control the mineral feed to ball mills when the falling stream hits the liners in free fall high energy impacts appear superimposed over the mon mill background noise as shown in
Comminution in ball mills and vertical mills differs fundamentally. In a ball mill, size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the .
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

Control the noise output of the ball mill during the material grinding by engineering measures 2 Control the speed of spread receive of noise First we need to pay more attention to the internal heat dissipation and the equipment maintenance for the ball mill will produce lots of heat during running Second if possible use ...
MS NOISE announces new effective noise reduction enclosures for the RETSCH PM400 model (soundproofing performance of -15dB(A). So -75% decrease in noise perception) MS Noise™ was created in 2005, and is focused on acoustic insulation in laboratories (noise reduction enclosures for many vacuum pumps models & forepumps models).

The ball mill is a commonly used grinding equipment for beneficiation production lines, but it has the disadvantages of high noise and short noise propagation distance. It not only seriously affects the working state of the staff, but also damages the staff's ears, causing serious harm to the staff's mental and physical health.
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables .
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
