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
The cement ball mill operation is more practical and the energy-saving effect is better. In terms of production capacity, the output of cement ball mill produced by us can be increased by 15% – 20% compared with the one made by other cement ball mill manufacturers, while the power consumption is reduced by 10%.
compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant. Moreover, as this paper seeks to demon-
