Additives such as clay, sand or iron ore result in the desired chemical composition. The MULTIDOS® H weighfeeders and MULTIDOS® VPD apron feeders feed the various materials into the raw mill accurately and reliably. The raw meal is then
Raw Material Drying-Grinding Cement Plant Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

27/02/2007· A raw mill is the equipment used to grind raw materials into " rawmix " during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.
Before being burned in the rotary kiln, the material from the blending bed and the aggregates are ground to a fine raw meal in large mills. The powdery material is then transported to the silo by a pneumatic conveyor system. Reliable monitoring of the level is essential for optimal raw material storage. Your benefit. Reliable. Reliable measurement ensures a continuous supply of raw material

Vertical raw mill is widely used in cement industry. In the process of cement production in cement plant, cement raw meal needs to be ground by grinding equipment before calcination. Cement raw meal includes limestone, gypsum, silica, clay, fly ash and other components. Because these materials are mixed together and have special properties, so there is a high requirement for the material suitability
Raw mill is also called raw material mill, which is the essential equipment in the production process of cement. It has large application such as raw mill in cement plant, building materials, metallurgy, electric power and stone industry, which is mainly used for the grinding as well as drying of cement raw materials and other materials.
