Nitrogen Protection pulverization system
Here is the title one h1 placeholder text
Classification:
Jet mill
Product Description
PRINCIPLE
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, cycloneseparator, collector and automatic controller. When the system is activated,nitrogen gas will be released into the system to 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.
Features
1.Suitable to pulverize flammable, explosive, easily oxidized and hygroscopic materials.
2.Operation of machine is controlled by advanced touch screen and PLC for full-auto control, It's easy to control oxygen content.
3.Nitrogen is recycled with very low consumption. Nitrogen purity control is higher than 99%.
4.According to Material property, you can choose to use Jet mill or ultra-fine mechanical pulverizer.
5.It's widely used in Sulphur, Cobalt, nickel, boron oxide and hygroscopic cosmetics so on.
