What is OptimizeIT Raw Mix Preparation? The consequences of poorly prepared raw meal are well known. High lime causes meal to be burned harder and refractory life drops. High alkalines may cause cyclone blockage and restrict the use of the cement produced. Moisture content rises and so does energy consumption.

A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.
