Why Crushing Mill May Have too Large Noise?

Raymond mill, which is one kind of crushing mills, is our most widely used in the production of flour milling equipment, in the process of normal production, the machine vibration will happen, what the reasons for this problem is that, read the following article you will understand, will not use the controls at an hour when there's an emergency. This crushing mill in vibration of the following reasons:

1, crushing mill level no good school.Host and reducer is not in the same horizontal plane, namely host connection and reducer connection chakras different heart.

2, the anchor bolt is loose.Raymond machines host not fixed, when the material to enter, the rotation of the motor, it can make host to sway, causing the vibration of the big fault, this happens, should immediately stop, tighten the anchor bolts.

3, feed fairly granular or too big.In this case, you should adjust the mill feed back, if carefully, feed particle size should be for reducing mill back to shoes.On the other hand, if the feed particle size is too large, you should increase back shoes, to fill the gap between the larger particles, realize grinding material layer.

4, check whether the material is piling up.The material has not been out caused by the vibration.

5, check the Raymond mill grinding roller and grinding ring if there is any damage, this is also the cause of vibration and noise, if this reason, the need to change roller mill or ring to remove the fault.




6, pressure is not enough, there is no continuity of incoming material.Mill has certain requirements, not only to the partical and also require continuous feeding, to maintain a certain pressure.In addition, less feed, hollow the machine works, make flour milling operation is not smooth, causing vibration.

7, grinding pressure is too high.In the grinding pressure more than 7-8 mpa, flour out of fine powder to the trend of the conglomerate.And eyes, pressure is too high, also easy cause vibration mill.

8, fan blade dirt, or uneven wear. The dust on the fan will lead to unbalanced blades rotating drive fan vibration, in this case, remove dust or to replace the blade.
