In the production of alumina powder, a Raymond miller is an ideal weapon to improve production efficiency and enhance product market competitiveness. This article will introduce to you 400 mesh alumina powder Raymond vertical mill.

 

Alumina (aluminum oxide) is usually a white amorphous powder. Its main physical and chemical properties are: high melting point and boiling point, good fluidity, and relatively stable chemical properties. It has a very important position in the mining and ceramic industries. The market demand is also relatively large. At present, my country's alumina micropowder industry is developing rapidly. Under the development trend of large-scale production of alumina micropowder, our company has created a Raymond vertical mill with ideal performance in response to the large-scale production requirements of 400 mesh alumina micropowder proposed by some customers. The machine can improve the performance in terms of production capacity and granularity, which can effectively meet the personalized production needs of customers.

Alumina Raymond miller integrates crushing, grinding, grading, drying and conveying. The system layout is compact, the structure design is reasonable, the environment adaptability is strong, and the floor space is small; it is equipped with an advanced PLC electronic control system with a high degree of automation. The microcomputer system controls the entire process of material grinding, and can automatically configure an ideal grinding plan that saves time and effort according to the actual grinding situation, reduces the number of repeated grindings, and reduces the probability of iron impurity incorporation; the single machine has strong production capacity and a large range of product sizes to meet Customer's 400 mesh production requirements; equipped with a new type of grinding roller sealing device, the system is sealed as a whole, which helps to create a safe and dust-free environmental protection workshop.

 

 

Raymond miller is also called raymond grinding roller mil, Raymond vertical mill, three roller mill. It is suitable for the preparation of ore powder and coal powder, such as the fine powder processing of raw material ore, gypsum ore, coal and other materials. From the appearance, it looks like a steel container erected, with air inlet and outlet, and a material inlet in the middle. There is a motor at the lower part of the Raymond miller to drive the internal grinding rod and the grinding disc to rotate to grind or grind the materials to be ground. The finished materials are blown up by the wind from the air inlet. There is a separator in the upper part of the grinding roller mill to separate the coarse and fine powder, The wind of the raymond roller mill is taken out and collected by the air outlet.

 

 

After years of practice and continuous improvement, the Raymond vertical mill has become more and more perfect in structure, with the advantages of high efficiency, low energy consumption, small footprint, low capital investment, and no pollution to the environment. Therefore, it is widely used in the grinding and processing of mineral materials in the fields of metallurgy, building materials, chemicals, mining, etc. It is suitable for processing non-flammable and explosive minerals with Mohs hardness below seven and humidity below 6%, such as gypsum, talc, and calcite. , Limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, Pengrun clay, medical stone, bauxite, iron oxide red, iron ore, etc. The fineness of the finished product is between 613 microns and 440 microns. Through the joint action of the analysis machine and the fan, the requirements of different users can be met.

 

After the Raymond vertical mill crushes the bulk raw material to the required feed size, the material is transported to the storage bin by the elevator, and then sent to the grinding cavity of the host machine by the electromagnetic vibrating feeder evenly, and then into the grinding cavity The material is ground between the grinding roller and the grinding ring. The ground powder is brought to the analyzer for classification by the airflow of the fan. The fine powder that reaches the fineness requirement enters the large cyclone collector through the pipe with the airflow for separation and collection. The finished product is discharged through the unloader. During the operation of the main engine, the blade system plays a very important role. It is located at the lower end of the grinding roller. During the same rotation of the shovel and the grinding roller, the material is shoveled and thrown between the rings of the grinding roller to form a cushion layer. The material layer is rotated by the grinding roller to generate an outward squeezing force to push the material. Crushing, thereby achieving the purpose of milling.

 

The Raymond grinding roller mill is mainly composed of a host, an analysis machine, a blower, a finished cyclone separator, a pipeline device, and a motor. The main engine is composed of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, a cover and a motor. Auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc. Users can choose flexibly according to site conditions.
