Jet Mill

The jet mill utilizes the energy of high-speed airflow or superheated steam to cause particles to impact, collide, and rub against each other, achieving ultrafine grinding.

It has no moving parts during the grinding process, making it easy to maintain. Its fully enclosed operation eliminates impurities, resulting in products with excellent particle size distribution, shape, purity, and dispersion.

Applications:

Jet mills are widely used in a variety of industries, including chemicals, mining, abrasives, refractory materials, battery materials, metallurgy, building materials, pharmaceuticals, ceramics, food, pesticides, feed, new materials, and environmental protection.

For example, in the chemical industry, they can be used to prepare ultrafine catalysts to increase petroleum cracking rates; in the pharmaceutical industry, they are used to refine drugs to enhance absorption; and in the food processing industry, they can be used to process fiber-rich diets and calcium-supplemented foods.
 

Working Principle:

During operation, compressed air is chilled, filtered, and dried before flowing through nozzles in a supersonic flow into the crushing chamber, causing the material to flow and accelerate.
The material experiences severe collision, friction, and cutting at the intersection of multiple nozzles, resulting in ultra-fine particle crushing.
The crushed material is transported by the rising airflow to the impeller classification zone, where the centrifugal force of the classifier and the pumping force of the fan separate the coarse and fine powders.
The coarse powder returns to the crushing chamber for further crushing, while the qualified fine powder is carried by the airflow into the cyclone collector.
The bag filter collects fine dust, and the induced draft fan discharges the purified air.
