LM Vertical Mill integrates crushing, drying, grinding, classifying and conveying together, and it is specialized in processing non-metallic minerals, pulverized coal and . ⑵ It is equipped with one device,which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration. 5.
1. High grinding efficiency and low power consumption. 2. Low metal consumption in unit product. 3. Bed grinding with low noise. 4. Negative pressure and low dust pollution. 5. The technical process is simple and material grinding, drying and separate can be achieved at the same time. 6. Small floor space, compact layout,.
Grinding roller just down there will be vibration, the operation of the procedures and parameters are normal, and the scene did not feel the vibration, after . When the outlet temperature of high-temperature fan changes, mill conditions will change, too high to the disc plate on the bed is not easy to form, too low can not dry.
Case 2: Cement Application. This plant was experiencing a buildup of process material on the blades of their 117” Raw Mill Fan. This buildup was causing vibration problems and the fan was being shut down three to four times a week to be cleaned. When these shutdowns occurred, production was stopped.
In general, the mill is running, the resulting sound is very regular, people hear and will not feel irritable. However, if the noise generated by the vertical roller mill is not normal and affects the normal operation of the person, the operator will have to consider whether the mill has failed.
