In the grinding process of Raymond mill, the machine will have faults for it will grind hard materials or the machine itself has problems. For these common faults, this article will give the related solutions and we do hope these will be useful.



Why does the Raymond mill has Serious Vibration?
It has the following reasons which will cause the machine vibration: it is not parallel with the horizontal plane when the machine is installed; foundation bolts are not tightened; material layer is too thin; oversize feeding material.
For these reasons, the experts provide the related solutions: reinstall the machine to ensure it is parallel with the horizontal plane; tighten the foundation bolts; increase the feed; crush large materials before feeding them into the Raymond mill.
What is the reason of low discharging powder amount of Raymond Mill?
Reason: the cyclone collector's locking powder system is not close and it will cause powder breath; Raymond mill shovel blade is worn seriously and the materials cannot be thrown to the air; air flue is blocked; pipeline has air leakage.
The solutions: fix the cyclone collector and make the locking powder can work; change the blade; clean the air flue; block the pipeline leakage place.
How to deal with the Final end products are too coarse or too thin?
The reasons include: the classifier vane is seriously worn and cannot perform its classifying function, resulting in overly coarse final products; the exhaust fan in the grinding system does not have a suitable air volume. To solve these: change the classifier vane or change the classifier; reduce the air volume or increase the air volume.
operators should adjust the gap properly according to requirement, making sure the two axles are concentric.
How to reduce the noise of the host?
It is because: feeding material amount is small, blade is worn seriously, foundation bolts are loose; materials are too hard; grinding roller, grinding ring is out of shape.
The related solutions: increase the feeding amount, increase the material thickness, replace the blades, tighten the foundation bolts, remove hard materials, and replace the grinding roller and grinding ring.
