Ball mill and classifying production line of silica powder
With the ultrafine processing of non-metallic minerals, ultrafine crushing and grading technology has become one of the most important deep processing technologies, which is of great significance to the development of modern high-tech industries.
Silicon micropowder (SiO2) is an extremely widely used inorganic non-metallic material, with acid and alkali corrosion resistance, abrasion resistance; high insulation, high thermal conductivity, high thermal stability; low expansion coefficient, low dielectric coefficient, and low thermal conductivity. It is widely used in the fields of chemicals, electronics, integrated circuits (IC), electrical appliances, plastics, coatings, advanced paints, rubber, and national defense.
According to the level, it is divided into ordinary silicon powder, electrical grade silicon powder, fused silicon powder, ultra-fine silicon powder, and spherical silicon powder; according to the purpose, it is divided into silicon powder for paint and coating, silicon powder for epoxy floor, silicon powder for rubber, and sealing Silicon powder for glue, electronic grade and electrical grade silicon powder for plastic packaging, and silicon powder for precision ceramics; according to the production process, it is divided into crystalline powder, cristobalite powder, fusion powder, and various active powders.
The preparation of crystalline powder, cristobalite powder, fusion powder and various active powders all need to go through a grinding and classification process. The grinding and classification of silicon micropowder generally adopts dry ball milling and classification.
Ball Mill and Classifying Production Line
All kinds of crushed, beneficiated, calcined or melted silicon powder raw materials → hoist → silo → electromagnetic vibrating feeder → ball mill → classifier → cyclone collector → bag dust collector
- Characteristics of ball mill classification production line
Large output, simple equipment operation, low maintenance costs, flexible selection of grinding media and liners, low pollution to high-purity processing of materials, reliable overall equipment operation, and stable product quality.
The application of silicon powder can make the product high in whiteness, good gloss and stable quality index.
- Ball mill classification production line output
In actual production, in order to maximize the benefits, the output matching of the ball mill and the classifier is very important. Proper cooperation can give full play to their own characteristics, complement each other’s advantages, and are highly efficient. Poor coordination will result in functional constraints, high energy consumption and low efficiency.
The influencing factors of the output of the ball mill include the fineness of the feed, the effective diameter of the mill body after lining, the speed of the ball mill, the selection and gradation of the ball mill media, the filling amount, the effective length of the mill body, and the size of the feeding amount.
The factors affecting the output of the classifier include powder concentration, turbine classifier speed, air volume and pressure, classification efficiency, particle size distribution, and product fineness.
Therefore, the output of the two equipment should have the following relationship: the output of the classifier = the processing capacity of the classifier-the amount of coarse material after classification; the output of the ball mill = the amount of raw material feeding + the return amount of coarse material after classification; the processing capacity of the classifier = The output of the ball mill.
Market Outlook of Silicon Micropowder
With the development of the high-tech industry, the use of silicon micropowder is becoming wider and wider, and the amount used is increasing. For the huge high-end market demand in the future, it is necessary to improve the quality of silicon raw materials, improve the technical level of silicon powder production, strengthen the testing and control of the production process, and break the technical barriers as soon as possible, so as to produce various specifications that meet the quality requirements of various fields according to market demand Silicon powder to meet the needs of domestic and foreign markets.
