Inert Gas Protection Crushing Process

Description: inert gas protection crushing processes are applicable for easily oxidized or nitride materials. Ultrafine grinding using inert gas system involves using as an inert gas as grinding media to achieve ultrafine grinding of dry materials. The system consists of a compressor, tank, hopper, crushing media, cyclone system, collector, automation control cabinet and other components.

 

The system begins by filling the system with an inert gas through the air system until reaching a set value detected by a sensor, following which, materials will be charged into the system through the hopper into the crushing chamber. Compressed inert gas enters through a specially configured nozzle of the high-speed jet to the crushing chamber, causing the material to accelerate causing repeated impact, collision, for the crushing effect. The crushed materials are crushed are brought to the classification zone via air movement from the jet. Under the strong centrifugal force generated by the air pressure, materials that meet the size requirements pass through and will be collected by the cyclone and the collecting system, while coarse particles fall back into the crushing chamber for further size reduction.

 

Features：

1. Inert gas can be changed to adapt to the grinding media, depending on the nature of the material.

2. Use of an inert gas circulation, reducing inert gas consumption.

3. Inert gas purity error can be controlled 1PPM, the oxygen content can be arbitrarily set.

4. Low wear factor, as particles are reduced in size through collision at high-speed with other particles with minimum friction with the wall, applicable for crushing materials of Mohs hardness below nine.

5. Wide range of grinding with output diameters from 2 - 15um.

6. The system uses an advanced touch screen, PLC programmable controller to achieve automatic control.

 

Application：used in chemical industry, metallurgy, abrasive, medicine, food, new materials and other industries, which require special treatment, the material is easily oxidized or nitrided crushing, grading.
