There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).
Therefore, to improve the ability of cement classifier is conducive to the full play of the grinding ability of the cement mill. The cement separator is an important part of the grinding system. The operation parameters of the cement separator are related to the production of the whole cement grinding unit. The higher the separation efficiency ...

Material is directly conveyed to the silos (silos are the large storage tanks of cement) from the grinding mills. Further, it is packed to about 2040 kg bags. Only a small percent of cement is packed in the bags only for those customers whom need is very small. The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships.
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.

Cement Milling. Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse ...
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 [.]
