Raw Mix Preparation - ABB

The consequences of poorly prepared raw meal are well known. High lime causes meal to be burned harder and refractory ITlife drops. High alkalines may cause cyclone blockage and restrict the use of the cement produced. Moisture content rises and so does energy consumption. And of course, oversize meal brings low reactivity and burnability. As leaders in kiln control and optimization using ...
