Vibration of cement vertical roller mill is a bad phenomenon, violent vibration will lead directly to a cement vertical mill shutdown, wear parts, finished production schedule and quality, so we must touch clear effect of vertical milling machine causes severe vibration, strictly grasp of a cement vertical mill every step of the operation steps, reduce may cause severe vibration reasons of cement vertical mill!
1, operation problem. A roller mill, high pressure material layer is too thin to cause operation of cement mill vibration. Users have a professional operation method in the production process, resulting in long-term control is too high and the material grinding pressure mill, cause grinding roller and the grinding disc wear. After the cement vertical mill boot normal work, the user for a cement vertical mill in the thickness of the material layer need to adjust the grinding and the pressure on the material, also in cement vertical mill shutdown is to promptly remove the grinding and the pressure of materials, such as cement vertical mill downtime recompression the grinding roll back. Caused by cement vertical mill vibration and material layer is too thin to the reason, material layer is too thin to cause grinding roller in roller compacted material will accidentally rolled to the disc, causing grinding roller and the grinding disc of the collision, resulting in vibration.
2, cement vertical mill grinding roller and grinding wear. Wear and abrasion and grinding force balance, easy to cause the vibration, and disc wear also makes the material on the disc thickness of material layer is not uniform, causing the machine vibration.
3, material feeding granularity is too large. Because the cement vertical grinding materials in the production of flour is after crushing into cement vertical mill, when the hardness of the material is relatively large, is not easy to break into cement vertical mill material particle size is larger, the bulk material will caused by wear and severe wear and damage, resulting in a machine abnormal vibration. Material particles through the big will cause the material can not be timely and piled up, resulting in machine vibration.
4, the material is too brittle. For some like brittle materials such as limestone, when they enter the cement vertical mill grinding cavity, in grinding and grinding under sudden rupture, resulting in grinding roller and the grinding disc between the sudden breaking phenomenon of material, and under the mill roller because no material, will hit the upper millstone, causing vibration of the machine.
