ball mill noise reduction

5 practical ways to reduce ball mill noise_cement

2019-7-9  On the whole, there are two ways to reduce noise in ball mill: one is to control the propagation of sound; the other is to start from the source of noise. The noise in the equipment operation is reduced, which creates a better working environment for the users, which can make the production of the equipment more continuous and efficient, and bring great benefits to the production.

Controlling ball mill noise with acoustic blankets: A

2009-10-6  However, treating the remaining two mills still proved to be very effective, further reducing ball mill noise in the near field by as much as 10.0 dBA and producing far field noise reductions of 3.0 dBA or greater, extending as far as 35 ft from the mills and to the floor above. The model developed from the survey data shows that a process attendant spending a substantial portion of a shift in the mill building will experience a significant reduction

Mill sound detection based on signal singular entropy

This article uses a kind of non-contact detection method to detect the ball mill load. Firstly, it uses a method based on singular entropy to proceed noise reduction processing of the measured grinding sound signal. Then extracts and analyzes the signal feature with FFT. Finally, we can obtain the conditions of the ball mill load.

12 Ways To Reduce Cutting Vibrations On Cnc Milling

2020-12-14  For the key cutting of the slender shank of the sharp knife, or the external turning of the slender shaft, the use of a tool with a 90 ° main declination is beneficial for vibration reduction. Whether it is an external turning tool turning a slender shaft or a keyhole in the keystone of a slender tool holder, it is always 90° and the tool with the main offset angle produces the least radial cutting force.
