Description

Technical Field

[0001] The utility model relates to the technical field of powder processing equipment, in particular to a grinding device for producing silicon carbide powder. Background Art

[0002] Silicon carbide, also known as corundum, is made of quartz sand, petroleum coke (or coal coke), sawdust (salt is needed to produce green silicon carbide) and other raw materials through high-temperature smelting in a resistance furnace. As an important material, silicon carbide has a complex production process, consumes a lot of energy, and has a high price. In the overall resource utilization link, the classification of silicon carbide powder is an industrial and device problem. Usually, it is classified using an airflow classifier. The micro powder enters the classification chamber of the airflow classifier. The centrifugal force generated by the rotation of the rotor is used to separate the powder mixed in the gas-solid two-phase fluid according to the particle size for classification and recovery. However, the raw materials used for classification will inevitably be mixed with larger silicon carbide particles or impurities. If they are not separated, it may affect the subsequent processing and reduce the purity of silicon carbide in the silicon carbide powder. In addition, the gas discharged after the silicon carbide powder is separated will inevitably be mixed with finer silicon carbide powder. If it is not collected, it will cause pollution to the environment and waste resources.

[0003] The patent name is "CN212349464U", which is published as: An airflow classifier for producing silicon carbide powder. The public document solves the above problems, but the shortcomings of the device in the public document are that when the airflow classifies the powder, the airflow will form wind force on the powder, causing the powder to fly freely inside the powder shell, and the powder cannot be quickly classified, which reduces the efficiency of powder classification. Based on this, the utility model designs a grinding device for silicon carbide powder production to solve the above problems. Utility Model Content
