Cement Production: Raw Meal Production in Steps Perfectly mixed, accurately fed without pulsation, and precisely weighed. The key word is quality! And this quality is achieved during cement production with exactly matched process steps. In the first stage, the raw meal is produced, as described below.

This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the "specific surface area", which is the total particle surface area ...
