For 1269 h of operation, cement mill no. 6 processed 92637 t of cement. The average performance of the mill is 73 t/h at the grinding fineness of 1011% (residue on the sieve no. 008). This fineness of grinding was achieved due to using highquality ShKh15 steel grinding balls with diameters of 25, 30, and 35 mm that retained its initial ...

The main difference to cement mill operation is the need to dry raw·feed and assure transport of stightly moist materialwithin a mill. Also, many raw materials are softer than clinker, and operations must avoid coarse residues in kiln feed that are difficult to combine in the kiln and would result in high clinkerfreelime, and/or excessive ...

The speed of rotation of the mill determines three basic types of operation modes: slow rotation (cascading), fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the charge in the mill and a different impact of the milling bodies on the ground material.

Clinker grinding technology is the most energyintensive 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 significantly, the [.]
