Nitrogen maintenance crushing equipment uses inert gas as the grinding medium for airflow crushing, completes ultra-fine crushing of dry materials, can cooperate with inert gas to stop crushing and classifying under closed-circuit circulating system, and stops classifying those materials which are very vulnerable to extinguishing, oxidation and explosion. For example, the crushing of carbonyl iron powder, nickel powder, tungsten-cobalt alloy powder, refined selenium powder, sulfur and so on, the inert gas returns to the air intake of the compressor for recycling, with less gas consumption and high automation level, and is suitable for various oxygen-sensitive materials and active materials. Because of the high cost of inert gases, closed-cycle systems are usually used, and strict air-tightness is used to separate the inlet and outlet.
1. Material collision stops crushing. The product has no iron pollution and can stop the mixing crushing of several materials.
2. It can be used in a wide range, and inert gases can be selected as maintenance gases according to the characteristics of flammable, explosive and oxidizable powders.
3. The purity of inert gas can be selected according to the requirements of process and product characteristics. The inert gas can be recycled with low loss.
4. Oxygen content in demand control system can reach below 1PPM.
5. The system has built-in oxygen content monitoring system to complete automatic nitrogen replenishment and pressure balancing.
7. The first graded flow field technology can achieve the best grinding efficiency and strict particle size distribution, with less material loss.
8. Fully sealed negative pressure operation, pulse automatic ash removal, using imported new high-precision ferry filter material, collection efficiency > 99.99%;
9. Emergency filters are designed after the dust collector to prevent unexpected dust from entering the compressor.
10. High level of automation and easy operation.
