Cement is produced from raw materials such as limestone, chalk, shale, clay, and sand. These raw materials are quarried, crushed, finely ground, and blended to the correct chemical composition. Small quantities of iron ore, alumina, and other minerals may be added to adjust the raw material composition.
Raw material ball mill, also called raw meal ball mill, is important grinding equipment in cement production process After being crushed, the raw meal enters the raw material mill The raw meal is grinded into fine powder by the motion and squeezing of steel balls The raw material mill manufactured by Great Wall Machinery can meet the raw material supply of 250~2500t d
Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used.
We produce cement raw material grinding mills in various specifications. These machines are suitable for grinding mill production lines with an output of 2500t/d, 3200t/d, 4000t/d, 5000t/d, 6000t/d, and 8000t/d. The vertical grinding mill is utilized to grind raw materials, mixed cement, and slag powder.
Vertical raw mill is one kind of raw mill, generally used to grind bulk, granular, and powder raw materials into required cement raw meal in the cement manufacturing plant.Vertical raw mill is an ideal grinding mill that crushing, drying, grinding, grading transfer set in one. It can be widely used in cement, electric power, metallurgy, chemical industry, non-metallic ore, and other industries.
2. Operating Status of Raw Material Mill System in China Cement Industry In cement production, the energy consumption of the grinding process is mainly reflected in the links of raw material preparation, coal powder preparation, and cement grinding. Though raw material grinding does not require higher specific surface area,
Grinding of cement raw material – material separation in cyclones. The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm).
Raw mill is generally called cement raw mill, raw mill in cement plant, it refers to a common type of cement equipment in the cement plant.In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.
