Vertical Roller Mill Operations

Vertical Roller Mill is popular for efficient grinding and separation of material. We discuss some recommendations for the mill when mill ΔP is too high, what are the possibilities?

Increase the grinding pressure, but:
Prone to increase the vibrations
Increase the mill kW

Decrease the mill feed rate, but:
Prone to increase the vibrations

Increase the mill ventilation, but:
Lost of the product fineness

If mill vibrations are too high, what are the recommendations ?

Decrease the grinding pressure, but:
Increase the ΔP

Increase the mill feed rate, but:
Increase the mill kW
Increase the ΔP

Increase the water injection, but:
Decrease the cement performances
