How to Reduce Noise of Ball Mill during Production?

How to control the noise generating of ball mill is a problem troubling many customers. In order to reduce noise and create a comfortable working environment, Hongxing Machinery gives some basic suggestions to control noise.

First, the most commonly used method is to add an acoustic shield whose outer surface is mainly made up of steel plate and its inner wall adopts sound absorption materials or superfine glass. The ball mill is sealed completely. But the thing worth attention is that it will produce much heat during functioning, so we should check its inner temperature and regular maintenance. Second, set an elastic layer which means to add a heat and wear resistant rubber cushion between the inner wall of cylinder and lining board of ball mill to avoid overheating of rubber. Besides we should set a blanket with a certain thickness between rubber and lining board of ball mill to reduce noise. We can replace steel lining board with rubber lining board which has a better effect to reduce noise. If the economic condition allows, we can put the milling equipment in an isolation booth. Thus the noise reduction effect will be better. But we should emphasize the problem to check the inner temperature and maintenance ball mill regularly.

If the ball mill temperature surpasses the normal index, it will bring great damage to its working efficiency and service life. Here are some methods based on different reasons of problem: 1, if the temperature of ball mill is too high, we should check the lubrication points of all parts to see if the lubrication brand is accordance with the instructions; 2, check if the lubrication oil is out of date; 3, check if the lubrication pipe is jammed or there is no sufficient oil; 4, the sealing device of hollow shaft on both ends of ball mill is too tight.
