the basic structure and working principle of the jet mill

Air flow mill, cyclone separator, Dust Collector and induced draft fan constitute a complete set of crushing system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber through Laval nozzle at high speed. At the meeting point of multiple high-pressure air streams, the materials are crushed by repeated collision, friction and shear. The crushed materials move to the classification area with the updraft under the action of fan pumping force. The fine particles that meet the size requirements are collected by the classifier into the cyclone separator and dust collector, and the coarse particles drop to the grinding zone for further grinding.

Airflow mill can be customized according to the needs of users, the material is divided into carbon steel and stainless steel two. Models of different sizes can also be customized according to output. For some inflammable and explosive nitrous oxide materials, closed circuit grinding can be achieved with inert gas, inert gas recycling, low loss, rational utilization of resources. To sum up, the jet mill can not only ultrafine pulverize any material, but also achieve no dust leakage, to achieve a very environmental protection level, it can be said to kill two birds with one stone.

The equipment can also be used in series of multistage Classifier, one time production of multiple granularity segments of the product. It has one of the biggest features is that the equipment is easy to disassemble and wash, the inner wall is smooth without dead corners. The whole equipment system closed crushing, less dust, dust collection device, low noise, clean and environmental protection production process. This is its great advantage, not only powerful, and the whole crushing process without any dust leakage. Achieved the requirements of environmental protection.
