Silicon carbide powder can be seen in concrete, refractory and other industries, and its application is very extensive. Its products have also achieved success in engineering boards, wear-resistant floors, coatings, functional mortar, etc. There are also developments in other fields, such as using silicon carbide powder to manufacture corresponding products under the condition of simplifying the process, which is ideal for high-temperature spraying, steel casting, etc. How is silicon carbide powder produced? Silicon Carbide Grinding Mill is a common silicon carbide production process. It is mainly produced by silicon carbide Raymond mill machine and its supporting equipment. HCMilling(Guilin Hongcheng) is the manufacturer of silicon carbide Raymond mill machine. Here is the production process of silicon carbide Raymond mill machine.

1. The raw material of silicon carbide is crushed with a crusher to screen silicon carbide particles of no more than 5mm, and then shaped into silicon carbide particles of no more than 2mm with a molding machine. The elliptical particles account for more than 80%, and then pickled and dried.

2. Grind the above silicon carbide dry particles into d50=9.5-11.5 with silicon carbide Raymond mill machine μ M of silicon carbide powder. During crushing, the main flow of the mill is set at 65-75a, and the fan flow is set at 40-50 m3/min. Analyzer speed 400-600 rpm

3. Then the silicon carbide powder is classified by a vortex air classifier. During classification, the fan flow of the gangue crusher vortex air classifier is 25~43m3 min, and the speed of the classification wheel is 2600 rpm/min. Particle size ds94=6.5~5.5 separated from the grading port μ M of finished product A, separated from the cyclone outlet, the semi-finished product ds94 ≤ 5.5 μ.

4. The swirling air classifier is divided into impeller type semi-finished air classifier and reclassified. During the classification process, the fan flow of the impeller air classifier is 25~10m3 min, the speed of the cascade wheel is 1300~700 rpm, the fan flow is 25~10m3 min, and the impeller speed is 1300~700 rpm. Final product B (ds94=4.5-3.0 μ m) It is separated from the classification port, and the by-product dryer equipment is separated from the cyclone port.

The above is the production process of silicon carbide Raymond mill machine. HC series silicon carbide Raymond mill machine produced by HCMilling(Guilin Hongcheng) has been widely used in the silicon carbide Raymond mill project, and has rich experience in the production and design of Raymond silicon carbide grinding.
