PDF Cement grinding Vertical roller mills versus ball mills

patent and started selling an improved version of this mill all over the world. For the cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding.


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 delay characteristics also dynamics changes within 2-4 minutes.

The cement kiln

Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.

Modern Processing Techniques to minimize cost in Cement

Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton. On an overall basis, VRM consumes about 20 % lower specific energy than conventional closed circuit ball mills and is being widely used for raw material and coal grinding in the cement industry.


the mill table, due to mill and roller’s relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place. The unstable grinding bed causes the VRM to vibrate. Water is directly sprayed into the bed to make dry mill feed, which is
