Weighing control system, high precision, optional, high product stability. Explosion-proof design for nitrogen circulation system to meet the ultra-fine grinding processing requirements of flammable and explosive oxide materials.

Product Description


The Nitrogen protection jet mill system uses Nitrogen gas as media for pneumatic mining to perform dry-process superfine pulverization. The jet mill system mainly consists of compressor, air storage tank, material storage tank, jet mill, cyclone separator, collector and automatic controller. When the system is activated, nitrogen gas will be released into the systemto drive the air out till the whole system reaches the numerical value fixed by the oxygen detector. Then the system will automatically start the material feeding device to feed the materials evenly into the milling chamber of the jet mill. The compressed nitrogen gas is injected at a high speed into the milling chamber by means of special ultrasonic nozzle.  Therefore, the materials will be ground by being accelerated, impacted and collided repeatedly in the midst Of ultrasonic injection flow. The ground materials will be brought together with upflow to the grading chamber. They cannot enter the grading wheel and will be swirled back into the milling chamber for further milling. The thinner grains will enter the grading wheel and be blasted to cyclone separator and collector whereas the nitrogen gas will return to the compressor, through Which it will be compressed for recycling.

Operational Principle

Our market

The flow chart is standard milling processing,and can be adjusted for customers.There are three parts for the whole system:Nitrogen manufacturing system,Nitrogen compression system,enclosed grinding system.
