The cause of temperature rise of the vertical roller mill is confirmed, the fault can be handled immediately by strengthening the ventilation in the barrel of the vertical roller mill; Water spray device can be added to spray water from the grinding head or tail.

The water spray cooling in the cylinder not only uses the sensible heat of water, but also uses the latent heat of water during evaporation, which effectively takes away the heat in the mill.

However, it should be noted that the water spray amount is about 1% - 1.5% of cement, generally not more than 2%, otherwise the water cannot be completely evaporated.

Vibration change and Countermeasures of vertical roller mill under normal operation, the vertical roller mill has no vibration sense.
