5 Ways to Control the Ball Mill Noise JXSC Machine

Introduction. The ball mill is indispensable grinding equipment in the ore beneficiation process.How to control the ball mill noise? Ball mill is mainly used for grinding materials in the industrial production process. Due to the large volume and heavy tonnage, the noise ( strong vibration and noise ) generated is usually above 95dB(A), which is serious affects the physical and mental health

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.

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.

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
