5 Ways to Control the Ball Mill Noise JXSC Machine

The ball mill noise is related to the diameter of the ball mill, the speed of the ball, and the nature and blockiness of the material. The ball mill noise is basically steady-state noise, wide frequency range, the larger the diameter, the stronger the low frequency noise. Methods of reducing ball mill noise

How to Control the Ball Mill Noise? JXSC Machine

Dec 19, 2019· The ball mill can Reduce the ball mill noise below the allowable standard. (3) The ball mill uses a rubber liner instead of a manganese steel liner. The noise level can be reduced by 9dB (A), and the frequency spectrum characteristics of the ball mill are also changed from high frequency to low frequency. Ball mill design soundproof room.

how to solve the noise of ball mill Hongxing Machinery

The solution about the noise of ball mill. 1.Acoustic enclosure (soundproof hood) Use the acoustic enclosure to cover the whole ball mill, and then add a sound absorbing device in the hood to eliminate the reverberation noise. This method usually gains the noise reduction of 25-45db (A), but it does not effectively isolate the ball mill

Ball Mills an overview ScienceDirect Topics

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 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.

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend 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 rotating about its axis. T

The reason and control method of ball mill noise

When grinding materials, the ball mill can produce strong vibration and noise, the noise is up to about 100~115dB, which is very harmful to the operator and the surrounding environment.. 1. Noise source and influencing factors of ball mill: (1) the ball mill level noise is related to the diameter and speed of the ball mill as well as the nature and lumpiness of the material.

Ball Mill an overview ScienceDirect Topics

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.
