Vibration Of Table Top Wet Ultrafine Mill
As we all know, Table Top Wet Ultrafine Mill is vertical structure, covers an especially small area, the system is simple, the technical requirements of the operator is low, the investment is relatively small, is a new type of energy saving equipment, favored by the enterprise, especially in the cement For a long time in the industry, it has been widely used. This kind of Table Top Wet Ultrafine Mill is defined as a Table Top Wet Ultrafine Mill, which is specially designed for the production of cement. In response to the development of the cement industry and market needs, we designed a new type of Table Top Wet Ultrafine Mill equipment cement manufacturers have been specially recognized, of which Changzhou plant designed LM series of medium-speed Table Top Wet Ultrafine Mill as its production of the host, and achieved very good results.
Maintenance personnel and operators repeatedly communicate, summed up some of the reasons for Table Top Wet Ultrafine Mill vibration and processing methods, written below:
First to note is that the vibration of the Table Top Wet Ultrafine Mill more common problems, especially just put into production of new Ultrafine Milling equipment, the vibration is mostly due to the roller and disc material layer thickness inappropriate or into the foreign body caused by the general situation Under the material into the grinding material is uneven, the bulk material and powder material together into the Ultrafine Mill, if the bulk material itself, or block size is too large blocks, or iron and other high hardness When foreign matter enters, due to segregation and inertial centrifugal force, the separation occurs. The massive materials on the grinding disc are mostly concentrated in the periphery, resulting in the uneven thickness of the material layer between the grinding roller and the grinding disc. The pressure of the grinding roller is unstable and even exceeds the limit , Resulting in Ultrafine Mill vibration; if the powdery material is too much, most of the material is brought into the Ultrafine Mill airflow, but also by the separator to disperse fall, will lead to Ultrafine Mill cycle load increases, so there will be between the Ultrafine Mill roll and disc Material layer is too thin, or the phenomenon of dry grinding, resulting in Ultrafine Mill vibration.
The solution: This situation can be controlled by strictly controlling the particle size of the material into the Ultrafine Mill, to ensure that the particle size into the Ultrafine Mill material qualified, and the material into the Ultrafine Mill speed, Ductile iron and other high-hardness materials into the Ultrafine Mill, to maintain a stable and uniform feeding Measures to solve the problem of uneven material thickness.
In addition, the pressure into the Ultrafine Mill airflow instability can also cause Ultrafine Mill vibration, especially the use of kiln exhaust Table Top Wet Ultrafine Mill, due to instability of feeding the rotary kiln, resulting in kiln exhaust gas pressure is unstable, with a large number of dust kiln Unstable tail airflow into the Ultrafine Mill cavity, resulting in increased Ultrafine Mill cycle load, resulting in Ultrafine Mill vibration. If this is the cause of Ultrafine Mill vibration, you can take to increase the ring blower valve opening to increase the amount of air into the Ultrafine Mill and negative pressure to stabilize the material thickness of the way to solve.
In addition, Table Top Wet Ultrafine Mill vibration may also have other reasons, it is recommended to find the manufacturer to solve their problems.
