The fineness and purity of the jet mill are the main performance “highlights”
The jet mill has various properties such as winnowing type, no screen, no net, uniform particle size, etc., and the production process is continuous. This machine has reached the international advanced level and is widely used in the grinding of materials in the pharmaceutical, chemical, food and other industries. It is suitable for the grinding of various non-metallic minerals, cement, building materials and other brittle materials. It can also be used for some materials difficult to achieve grinding fineness. The jet mill adopts purified and dry compressed gas, which is jetted into the grinding chamber at a high speed through a special supersonic nozzle. The air flow carries the material at high speed, causing strong collision, friction and shearing between the material and the material to achieve the purpose of grinding.The ground material rises into the classification chamber, the material that meets the particle size requirements passes through the forced impeller classifier, and the particles that do not meet the particle size requirements return to the grinding chamber to continue grinding.
The entire production process is fully enclosed and continuous operation, no dust pollution, and the air is purified after dust removal and filtration. The grinding principle of the jet mill determines the typical characteristics of the machine such as wide application range, fine particle size and high product purity. It can be matched with inert gas to form a new type of inert gas closed-circuit protection grinding production line, which is widely used in flammable, explosive, easy to oxidize, etc. grinding processing of materials.
The reason why the jet mill is favored by the majority of users is mainly because it has many “highlights”, one is “fineness”, as the name suggests is how fine the jet mill can grind, and the application requirements of various industries are different, how Achieving the established fineness is the primary consideration when designing and manufacturing. Various materials require different grinding fineness, depending on the applicable industry and the requirements for material grinding. The second is “purity”, which requires no pollution during the grinding process and the original composition should be maintained. Many materials will have some chemical effects during grinding due to temperature, humidity and other reasons, especially in the pharmaceutical industry of Chinese herbal medicine grinding, this is even more important. Therefore, the temperature, humidity and other conditions of the material must be considered in the design. The airflow of the jet mill must have a high speed in order to generate a lot of energy. Therefore, increasing the air velocity of the nozzle is beneficial to improving the material grinding effect and grinding efficiency. However, if the pursuit of high speed is too high, energy consumption must be increased.
