Db of ball mill

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

  • 5 Ways to Control the Ball Mill Noise - JXSC Machine

    5 Ways to Control the Ball Mill Noise - JXSC Machine

    Oct 08, 2019 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 Install gear correctly

    Ball Mills - an overview | ScienceDirect Topics

    8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
