PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL

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.

Juice Extraction Performance in Milling Tandem in sugar

Primary Extraction The greater the extraction of sugar in the first mill the less difficult in the task left to the following mills to recover more sugar by the trouble some step of wet extraction and better is the overall extraction of the tandem.
