The coarser, portion of the cement is fed back into the mill for further grinding. (iv) Packing and Storage of Cement: This also forms a very important operational step since cement needs very careful packing and storage arrangements. It is, in fact, a delicate product and when handled carelessly can deteriorate to a useless set material.

Importance of fineness of cement. More cement coarse particles affect and reduce the rate of hydration. If the hydration rate decreases, then it impacts the strength development of concrete or mortar. More fineness induces dry cracks on concrete surfaces. Fineness cement can easily blend with other ingredients.

Cement Grinding: cement grinding is the final stage in Portland cement manufacturing. In this step, clinker will be ground in grinding mill to reach the qualified fineness of cement product. During the grinding, we usually add gypsum, fly ash and other raw materials into the cement to realize the different usage of cement.

The calcium sulfate is added to control the rate of early reaction of the cement Cement is produced by grinding clinker with gypsum (calcium sulfate) in the finish-grinding mill to a required fineness. A small quantity of gypsum, about 3 to 5 %, is needed to control the setting time of cement produced. The amount of gypsum being used is ...
