In the recent years, environmental protection attracts more and more of our attention. Mining Manufacturers’ attach great important to it during the design of stone crushing and grinding Machines.
As we know, when the ball is running, strong vibration and noise will be produced. The noise can reach to about 100 to 115 dB (A) that will badly influence the workers’ health.
How to control the noise of ball mil in the course of grinding materials?
The key point is to:
1. 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 rubber liner plate instead of manganese steel plate. Then, the noise will decrease at 9 dB (A), and then the high frequency spectrum characteristic changes to the low frequency spectrum characteristics.
Third, install a heat soft rubber between the inner surface of ball mill roller and the liner. That is to prevent overheating of the soft rubber plate put industrial felt whose thickness is 10-15mm between the ball mill plate and soft rubber pad lining board to decrease the noise of the ball mill to the required standard.
