Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly ...

The crushing and pulverizing process is carried out separately for each material. After grinding, each of the materials is stored in hoppers. 2. Mixing Storage. The raw materials are then mixed in correct proportions in dry powdered form with the help of compressed air. This finely ground powder of the raw materials is called raw mix.

All except soft materials are first crushed, often in two stages, and then ground, usually in a rotating, cylindrical ball, or tube mills containing a charge of steel grinding balls. This grinding is done wet or dry, depending on the process in use, but for dry grinding the raw materials first may need to be dried in cylindrical, rotary dryers.

Raw mill is the grinding equipment applied in the raw material preparation process. In the wet process of cement production, raw materials should be ground into raw slurry with a water content of 30% 40%. While in the dry process of cement production, they will be ground into dry powder in cement raw mill.
