Energy Consumption Cement Vertical Raw Mill Cement mill Wikipedia A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln in. Reducing energy consumption of a raw mill in cement Cement production in the world is currently about 16 billion ton per year About 2% of the electricity produced in the

In RMG, it takes about 30–40 min for the raw materials to enter the vertical mill (VM) and be fully pulverized , so there is a varying degree of delay between the system-related variables data and the corresponding energy consumption data . During the process of system operation, the state of system variables is constantly changing. The combination of these adverse factors makes it

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 delay

From the perspective of the design calculation, the unit raw meal power consumption of the roller press grinding system is about 3.5kwh/t lower than that of the vertical mill, which is equivalent to the clinker power consumption of 5.25kwh/t.
