The normal temperature jet pulverizer means that the air compressed by the air compressor is cooled by the refrigerating machine and then released as a medium through the Laval nozzle, which generates supersonic speed and is used for the crushing of powder materials.
It is suitable for the crushing application of a large number of powders.

The high temperature jet mill refers to: the air compressed by the air compressor is heated by the air heater, released as the medium through the Laval nozzle or the hot steam generated by the boiler is used as the medium,
It is released through the Laval nozzle to generate supersonic speed for the crushing of powder materials.

The low temperature jet mill refers to the nitrogen or carbon dioxide compressed by the air compressor, which is released through the Laval nozzle to generate supersonic speed for the crushing of powder materials.

The closed-loop jet pulverizer generally refers to connecting the air outlet of the pulse dust collector with the air inlet of the air compressor that provides the power source for the system on the basis of the jet pulverizer to form a closed system.
The crushing medium (air or inert gas such as nitrogen, argon, helium, carbon dioxide, etc.) of the whole crushing process is circulated in the closed system.

The fluidized bed jet mill is called jet mill for short. It has a simple structure and a wide range of applications, and is widely used in the powder industry.
