About Jinghua

Jet mill is a kind of equipment that uses high-speed airflow to achieve dry ultra-fine grinding of materials. Most common ones on the market are fluidized bed type and disc type. The filtered and dried compressed air is accelerated through the Laval nozzle and injected into the crushing zone at supersonic speed. The materials are fluidized and accelerated in the supersonic jet, and impact and collide with each other at the intersection formed by multiple nozzles to be crushed. The crushed material rises along the air flow to the classification area and is classified in time. The coarse material falls along the cylinder wall to the crushing area to continue crushing. The qualified fine powder is collected by subsequent equipment.

The air classifier performs centrifugal classification according to the different size and density of powder particles. It is mainly used for dry airflow classification of ultrafine powder materials. It can be connected in series to form a crushing-classifying complete system with various crushing units to make the ultrafine powder processing equipment more reasonable and economical. At the same time, for flammable, explosive, and oxidizable materials it can be operated under the protection of inert gas as a medium to make it safer.

The ultrafine impact mill is researched and developed based on the characteristics of many types of mechanical mills domestic and foreign and combined with the company's many years of powder engineering experience. It integrates a unique crushing mechanism and classification technology and has the functions of ultrafine crushing, scattering and shaping.
