Raw Mill Optimization 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 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
the mill During grinding the PSD changes progressively hence results can differ a lot at different finenesses energy consumption levels or grinding times In a two component system some general trends have been observed In the early period of grinding at low fineness the harder component will enrich in the coarser fraction and the softer will dominate the finer fraction of the PSD The
