The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
At the beginning stage when vertical roller mill was adopted to cement manufacturing, mill gas circulation fan and dust collection fan are required and their power consumption was larger. Descriptions The conventional process gas flow of the mill grinding system generally consists of

Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor
significantly reduces overall specific power consumption and increases system production. In ball mills, less power is required to produce finished cement from HRP-pressed material than from unpressed material. High electrical energy efficiency HRP has the highest grinding pressure (KN/m2)
Otherwise, I must say that, in closed circuit, it is not a bad approximation to assume that power consumption is proportional to the specific surface. In this case, the hourly production should be inverse-proportional to the specific surface, assuming constant mill power absorption.
