Cement Raw Comminution

Summary 22 cement raw mix samples from different parts of the world were analyzed to assess the influence of hard particles such as quartz on the wear in closed-circuit comminution equipment. So far the main belief has been that the concentration of quartz in the separator sample will return feed result in a strong correlation to the wear rate and that limestone will act as a diluting .

    Industrial Experience With Clinker Grinding In The

    Abstract Comminution is an important element for cost evaluation in any cement plant mainly in relation to the power consumed which is about 80 to 90 kW for a cement plant. In the early 90s grinding in cement plants was operated mainly by vertical mills for raw material with rather good results in the majority of cases and by tube mills for cement with some development of mixed grinding .
