Nov 02, 2015· re High Exit vent temp at cement mill outlet. Hi there, Well it's known that more than 85% of the energy in the ball mill is converted into heat and not used to grind the material. The heat is generated when the ball impact each other and this is the source of your heat in the mill.
In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.
temperature of the main flame. Temperature of the main flame also has a direct influence on clinker quality. If it is too low, any resulting clinker will lack sufficient quality. If it is too high, any resulting clinker will be of sufficient quality, except that it'll be too hard and require more energy at the cement mill. Raw mill …
