Residence time distributions normalized by mean residence time as a function of feed rate for centrifugal mill operated at G/D = 0.4, 60% ball filling, and mill revolution speed of 240 rpm. However, it was found that the shape of the RTD was changed somewhat with an increase in the mill revolution speed, as shown in Fig. 7 .
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. read more
