Recently I saw a lot of friends message consulting vertical mill related technical problems, the highest frequency of which is the main body of the vertical mill vibration phenomenon how to deal with, I learned after consulting, summarized a few common causes to share with you, I hope to help you.
Vertical Grinding Mill
Before solving the problem, the first thing to do is to find the problem, only to find the root cause of the failure to be able to solve.
1, the feed size is too large is the most frequent cause of failure, the feed size is not within the requirements of the mill, encounter this situation to strictly control the feed size can be avoided.
2, the material layer is not stable, in the face of this situation, it is necessary to ensure that the feeding volume of stable transport, in the case of conditions recommended the use of belt conveyor uniform feeding or change the height of the retaining ring, so that the material can form a stable layer, or when dealing with certain special materials, you can spray water in the mill cavity, which helps stabilize the material layer.
3, wind power is not enough or into the mill out of the grinding sub-pipe, dust collector blockage, must be checked in time, if there is no blockage vibration still exists, to increase the wind power of the fan.
4, grinding roller pressure is not appropriate, in the event of inappropriate grinding roller pressure problem, should be adjusted in time to avoid the host continue to violent vibration.
5, the roller sleeve and liner plate can not be in direct contact, will produce violent vibration, there should be an appropriate gap between the two.
6, the vertical mill internal into foreign objects, at this time, you need to remove foreign objects as soon as possible, while checking whether the iron remover is abnormal.
7, the material layer is too thin, for this situation, to adjust the feed volume, so that the material can quickly enter the vertical mill
8、The accumulator inflation pressure is too high, which causes the vertical mill to vibrate violently. In this case, pay attention to check the accumulator inflation pressure, if the value is abnormal, make corrections in time.
9、The liner plate and grinding roller set are seriously worn. At this time, it is necessary to replace our liner plate and roller sleeve.
The above is a small part of the vertical mill vibration for you to share a few common causes, at the same time should not ignore some other possible, causing the machine vibration abnormalities and many other factors, the face of this situation to seriously analyze to find out the cause, in order to be able to deal with abnormalities in a timely manner, but also very welcome to seek after-sales service, to get professional help.
