Optimization of Cement Grinding Operation in Ball Mills. Contact Us » . Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pre-grinders with ball mills.
The clinker is a kiln outlet, which is the main cement ingredient The limestone is used only for the cement production, for certain cement types, in the cement mill as a mineral component. The raw materials from the depo centre are transported to the vertical roller mill, where raw meal is produced. The storage of this raw meal consists of 2 silos.
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.

In the cement production line, producing 1 ton of Cement need grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials,gypsum).Grinding operation consumes about 60% of total power in cement plants, raw material grinding more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%.
The vertical mill can dry the material with 12%-15% moisture, and the drying ability is strong. Even if the ball mill is dried, only the material with moisture content of 3%-4% can be dried. . Therefore, vertical mills are used for the production of materials with large moisture content, which not only saves economic costs, but also saves time
