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 silica in the feed ...
Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
It is an excellent cement raw material. Classifiion: High Calcium Marl: CaO ≥ 45% ; Low calcium marl: CaO <45%. In some places, the composition of marl is close to the raw material for making cement. It can be directly fired into cement, which is called natural cement rock. Main mineral is calcite.
To make cement, the clinker must first be cooled. Prior to being crushed in the cement mill, the gypsum produced in the kiln is separated from the main product stream. The output from the cement mill may be blended with other constituents to meet certain specifiions depending on the end use. The packaged product is then shipped to the consumers.

This hard, pebble like material is the ingredient in cement which causes it to "cure" and harden to form the mortar or concrete used so extensively in construction.
The tubemill crushers are generally provided with air separators through which material of desired fineness can only pass. The coarser, portion of the cement is fed back into the mill for further grinding. (iv) Packing and Storage of Cement:
Grinding Aids are used in the cement mill (Ball Mill, Vertical Roller Mill, HoroMill) to increase the productivity, save electrical energy and/or to increase the fineness and improve defined cement properties, powder flowability. A typical example is SikaGrind®400.
For raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product quality. Further, our vertical roller mill solution for cement grinding has an ability to dry, grind and separate within a single ...
