Cement ball mill is a well known machine to grind raw material (hard clinker) into grey powder: Cement. A cement ball mill is a horizontal cylinder which is partly filled with steel balls of different sizes along with clinker (raw material) and rotates about its axis which provides tumbling action in ball mill which in turn grind raw material into …

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …

However, stirred mills can be applied to cement grinding if the feed size is made suitable. For example, instead of regrinding the separator reject in the tube mill, it can be directed to a stirred mill. Thus a possible energy saving can be obtained compared to ball mill grinding. Because, stirred mills are reported to supply energy savings ...
