Important Operation Tips For Cement Vertical Mill

The proper thickness of the layer and stable layer are basis for stable operation. The material layer is too thick will lead to grinding efficiency reduction, and when pressure difference of the mill reaches the limit, the material will collapse, which will affect main motor and venting system If material layer is too thin, with driving force of the mill increases, the grinding roller, disc and hydraulic system are damaged.

When the material is too fine, especially when the internal pressure difference of the vertical mill has risen significantly, the feeding should be adjusted in time, grinding pressure and outlet temperature should be reduced and the water spray amount should be increased, powder separator speed should be appropriately reduced. The grinding pressure is increased under the premise of ensuring stable pressure difference and layer thickness.

The accumulator mainly provides cushioning for the lifting of the roller set. If the pressure of the accumulator is too high or the nitrogen balloon is broken, the buffering effect will be reduced or even completely lost, resulting in a hard impact of the grinding roller group and the material bed causing severe vibration of the mill.

Feeding is large and satiety is a major cause.nbspHowever, when the material is poor in wearability, it will also slag.nbspThe size of the grinding material is large, the system air volume is insufficient, the grinding pressure is low, the system leaks air, the material layer is unstable, the material ring is low, and the roller surface or the grinding disc wears seriously, which will cause the grinding machine to slag more.nbsp.

When the raw material is running in the vertical mill, the drying heat source of the material comes from the hot gas at the kiln tail. Therefore, when the vertical mill is operated, the control of the inlet and outlet dampers should be balanced by the kiln mill.nbspWhen the vertical mill inlet and outlet dampers are balanced, the system39s wind will be balanced and will not affect the pressure at the kiln end.
