The pneumatic pulverizer can adjust the particle size, with excellent effect EPIC Powder Machinery

Airflow pulverizer is a large superfine pulverizer that mainly uses air flow for pulverization. Large machines also have high output. Airflow pulverizer is a complete set of pulverizing system consisting of air flow pulverizer, cyclone separator, dust remover and induced draft fan. The pulverizing process of air flow pulverizer is that compressed air is filtered and dried, and then injected into the pulverizing chamber through a high-speed nozzle. After being sprayed by a high-pressure air flow, a junction is formed, where materials are repeatedly impacted, rubbed and sheared to achieve pulverization. In order to achieve the required particle size, the air flow pulverizer is equipped with a classifier to grade different particle sizes, Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator and dust remover through the classification wheel for collection, while the coarse particles that do not meet the particle size requirements drop to the crushing area for further crushing. This is the main working process of air jet mill

Airflow mill has many advantages in the crushing process. It can crush materials with high hardness. It is more suitable for dry crushing of materials with Mohs hardness below 9. It is very effective for crushing materials with high hardness, high purity and high added value; The particle size distribution of the materials crushed by the air flow mill is D97=3-74 microns, and the particle size can be adjusted. The particle size is relatively good and the particle size distribution is narrow; In the crushing process, the air flow mill can be used for low temperature and ultra-low temperature media free crushing, and is also suitable for the crushing of heat sensitive, low melting point, sugar and volatile materials. Unlike the crushing method of other types of pulverizers, the air flow pulverizer mainly relies on the collision of materials themselves, which is different from the mechanical pulverization which relies on the crushing of materials by blades or hammers. In general, the air flow pulverizer is relatively wear-resistant and has high product purity. The air flow pulverizer is also easy to disassemble and wash, the inner wall is smooth without dead angle, and the whole system is closed for pulverization in the working process, so there is no dust pollution in the pulverization process, the noise is relatively low, and the production process fully meets the environmental protection requirements. With the development of air flow pulverizer, it can be applied to superfine pulverization in chemical, food, feed, pesticide, cosmetics and other industries. Qingdao EPIC Powder Machinery has also been continuously investing in the development of jet mill in recent years. It has more advanced technology and equipment in the industry, relatively cheap prices, and high-quality after-sales services. Users are welcome to come to our company to consult related businesses
