ultrafine mill plays an irreplaceable role in the ultrafine process and process of silicon carbide
The demand for
of silicon carbide is broad, and fake products may appear.
Ultra-fine grinding is a special equipment for processing high-fineness silicon carbide. At present, there are not many ultrafine mill manufacturers in China. The development of ultrafine mill in Shanghai, Fujian, Shandong and other places is better. In recent years, with the rapid development of the economy, the demand for processing and utilization of ultrafine mill production lines has also been greatly enhanced. However, there are also some ultrafine mill manufacturers who claim to produce silicon carbide superfine grinding products, which is worthy of serious study.
What are the processing steps for the silicon carbide ultrafine mill line?
1. Take the silicon carbide raw material, crush it by crusher, and sieve it to silicon carbide particles of not more than 5mm, and then shape it to silicon carbide particles of not more than 2mm with a shaping machine, and the oval particles account for more than 80%. , then pickling and removing impurities and drying;
2. The dried silicon carbide particles are pulverized into a silicon carbide powder having a d50=9.5-11.5 μm by a mill. When pulverized, the main current of the mill is set to 65-75 A, and the fan flow rate is set to 40-50 m3. /min, the speed of the analyzer is 400-600 rpm;
3. The SiC powder is then classified by a vortex flow classifier. When grading, the fan flow rate of the vortex flow classifier is 25-43 m3/min, and the grading wheel speed is 2600-3300 rpm. Finished product A with a particle size of ds94=6.5-5.5 μm, and a semi-finished product with ds94≤5.5 μm is separated from the cyclone;
4. The semi-finished product separated by the vortex flow classifier cyclone is further classified by the impeller type airflow classifier. When classifying, the flow rate of the fan of the impeller type air classifier is 25-10m3/min, and the speed of the classifying wheel is 1300- -1700 rpm, the finished product B having a particle size of ds94=4.5-3.0 μm is separated from the classification port, and the by-product is separated by the cyclone.
Shanghai Shibang's self-developed
products have been in the milling industry.
Such processes and processes are inseparable from the grinding equipment in mining machinery. Shanghai Shibang Machinery Co., Ltd. is a large-scale enterprise specializing in the production of milling machines. It not only has excellent product quality, but also reproduces the mining machinery industry with innovation. Shanghai Shibang's self-developed grinding machine new products have been far away in the same industry, such as: MTM ladder mill, SCM ultrafine superfine mill, YGM Raymond mill, MXB free hem mill, LM stand Mill, MTW European version of trapezoidal mill, Raymond mill, trapezoidal mill, medium speed mill, ultrafine ultrafine mill, coarse powder mill, coarse grinding, free hem grinding, vertical grinding, European version of grinding , pulverizer, pulverizing equipment, grinding machine, milling machine, milling equipment, milling machinery, etc. These equipments not only solve the current problems for many industries, but also bring high economic benefits to customers, winning users. Praise and favor.
Characteristics of SCM series micro-grinding production line
Among them, SCM series ultrafine powder grinding machine is Shanghai Shibang Machinery Co., Ltd. based on years of experience in grinding machine production, absorbing the advantages of domestic and foreign mill manufacturers, after fully inspecting, researching and testing 12 kinds of milling machines and horizontal The ring hammer pulverizer has developed a high-efficiency and low-cost ultrafine mill through many researches and experiments. Ultra-fine grinding production line product features:
1. Efficient. In the case of the same fineness of the finished product and the same motor power, the output is 40% higher than that of the jet mill and the agitator mill.
2. The wearing parts are highly utilized. In the case of the same material and finished product fineness, the wear parts of the impact crusher and the turbo crusher have a longer service life, generally more than one year.
3. High safety and reliability. Since there is no rolling bearing or screw in the grinding cavity, there is no problem that the bearing and its sealing member are vulnerable, and there is no problem that the screw is loose and the machine is destroyed.
