The cement plant raw meal mill is a device that grinds raw materials into raw meals of appropriate fineness and quality to provide uniform raw materials for the next step of cement firing production.
The working principle of the raw material mill is: that the raw materials are continuously ground and compressed under the action of the grinding disc and the grinding roller, and finally form a certain powdery material. At the same time, the raw meal mill is equipped with a circulating fan and a classifier to separate the powder that reaches the set particle size for subsequent production.
In the cement production process, the raw meal mill is an important link, which directly affects the quality and output of cement. Therefore, selecting appropriate raw mill equipment and process parameters is of great significance for improving the efficiency of cement production and reducing costs.
Raw mill equipment in cement plants mainly includes ball mills and roller presses.
• Ball Mill: This is one of the most commonly used mills in cement production. It uses a rotating grinding body to grind materials and is mainly used for grinding limestone, coal, and other materials in cement manufacturing. The advantages of a ball mill are high production efficiency and good grinding fineness, but it also has disadvantages such as high energy consumption and loud noise.
• Roller press: This is a new type of cement mill that uses crushing and friction to grind materials, which can achieve efficient material grinding. The advantages of the roller press are good grinding fineness and low energy consumption, but the disadvantage is that its adaptability to materials is not as good as the ball mill.
In addition, other equipment is used in the cement production process, such as jaw crushers, cone crushers, impact crushers, bucket elevators, iron removers, centrifugal pumps, dust collectors, vibrating screens, and scrapers. Machine, rotary kiln, etc. Among them, vertical mills, European mills, trapezoidal mills, and Raymond mills can also be used for cement grinding. The selection and use of these pieces of equipment are of great significance to improving the efficiency and reducing costs of cement production.
