The ultrafine pulverization equipment of jet mill belongs to the dry pulverization category in the physical method. Airflow superfine pulverizer. At present, it is widely used in industry and enjoys a reputation for its simple structure, fine product, narrow distribution, and high purity.

Jet mill ultrafine crushing equipment has the following basic types:

(1) Horizontal disc jet mill.

(2) Circulating tubular jet mill.

(3) Counter-jet (reverse) jet mill.

(4) Impact plate type (target type) jet mill.

(5) Fluidized bed jet mill.

Among the above five types of jet mills, the fluidized bed jet mill ultrafine pulverizer is the latest generation of jet pulverizer developed.

The ultra-fine pulverization equipment of the fluidized bed jet mill integrates multi-nozzle technology, fluidized bed technology and horizontal classification technology, and realizes the diversification of the flow field and the fluidization of the material layer and the horizontal classification system. In addition, a number of new technologies such as gas sealing are used to ensure the safe, efficient and stable operation of the machine.

In addition, the machine also has the following features:

(1) The crushing and classification of low melting point, heat sensitive, abrasive materials, metal ores and non-metallic ores cannot be replaced by any other mechanical method. The system is almost wear-free and the powder purity is extremely high.

(2) As the airflow accelerates and expands rapidly, its static temperature drops, so the crushing process is carried out instantaneously at low temperatures.

(3) Adopting multi-nozzle supersonic fluidized bed airflow crushing, low energy consumption, high crushing intensity, can crush materials above Mohs level 9 and at the same time ensure the purity of ultra-fine powder.

(4) Equipped with a high-precision classifier, by adjusting the speed of the classifier and system parameters, products with fine particle size, high purity and narrow particle size distribution can be obtained.

(5) The system has undergone multiple dust collection treatments, and there is almost no dust flying, which is beneficial to environmental protection.

Because the fluidized bed jet mill ultra-fine grinding equipment saves energy, has low wear, compact structure, small size, and large capacity, it has a unique effect on the heat sensitivity and the pulverization of fiber materials. At the same time, it has attracted great attention from the crushing industry at home and abroad. The current application field of this machine is expanding, which is a great challenge to the traditional jet mill.
