Cement grinding is the last process of cement production, it is to mix cement clinker and a small amount of gypsum, and then grind the mixture to a certain fineness, that is cement. You may also interest in the ball mill product price, lime ball mill, quartz ball mill .
Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other chemical additives to produce cement.
After cooling and storage, the clinker is ground into a fine cement powder and gypsum is added, as a source of calcium sulphate, to improve the future setting behaviour of the cement.

Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.
In the process of cement production, cement raw meal is calcined in a rotary kiln to obtain cement clinker. After the cement clinker is cooled, adding an appropriate amount of gypsum and additives. Put the mixture into cement mill and grinding to the appropriate particle size, so as to obtain the finished cement products.
Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement …

The dehydration of gypsum in the cement mill was simulated in the laboratory by grinding clinker with gypsum to form cement, and then dehydrating the gypsum by heating the cements for various periods.
Answer (1 of 2): Clinker is the main raw material used for cement manufacturing. The lime stone powder, iron ore, alumina are all made into a powery form and the same will be preheated and this preheated material will be sent thro' a rotary kiln and coal powder will …
Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4.2H 2 O).
Gypsum added to and ground with clinker regulates the setting time and gives the most important property of cement, compressive strength. It also prevents agglomeration and coating of the powder at the surface of balls and mill wall.
