Grinding of mill rolls is carried out with chatter resistant abrasive grinding wheels having relatively low elastic modulus values and relatively high burst speed values. Grinding operations may be carried out at high efficiency with controlled wheel vibration, thus generating optimum surface quality on the ground mill rolls.

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

Faulty grinding operation: Prevent wheel edge from digging in workpiece. Grind workpiece under light load which provides low grinding force, and use additional steady rests so that it cannot be inclined by grinding force. Reduce table speed or change some speed per pass. Spiral feed marks: Contact with wheel edge: Round off wheel edges. Wrong ...
