NdFeB air classifier/jet mill/pulverizer/milling machine

    Inflammable and Explosive Powder Grinder and Classifier was developed for grinding inflammable and explosive powder

in supersonic speed with inert gas. Since the inert gas is expensive, the enclosed and circular system is often adopted. 

Features

1. Improved grinding efficiency, energy saving without over-ground fineness;

2. Effective for hard materials (Mohs 1-10) with little wear and no iron contamination; 

3. Grinding several kinds of materials at one time;

4. Broad applications;  

5. Controlled purity of inert gas;  

6. Recycling inert gas with a small loss 

7. Effective for heat-sensative and low melting point materials under cold or normal temperature;

8. Well-distributed particle size;

9. Effective for dispersing agglomerate ultrafine powder;

10. Adjustable particle size 1-74µm (the powder can be ground down to submicron range);

11. High collecting efficiency (up to 99.9%);

12. Easy to operate due to PLC (Programmable Logic Controller) control system.

1.Materials collision each other without contamination, effective for Mohs 1-10 hard material

2.Widely used inflammable, explosive and easily oxidative material.

3.Depending on the requirements of process and material properties control the purity of inert gas, the recycling of inert gas causes little loss.

4.Controlling the oxygen content on specific requirement, it can be achieved to below 1PPM.

5.Self-equipped oxygen content detection system to reach the pressure balance and add Nitrogen automatically.

6.Optimization classification impeller structure, completely and stable flow effective for precision classifying. 

7.Particle size can be adjusted between 2~74um by original technology, the finest particle can up to submicron.

8.Collecting efficiency can be up to 99.99%; seal negative pressure operation without contamination

9.Emergency filter installed behind of dust collector to prevent powder into compressor. 

10.Fully automatic PLC control, easy to operate.

 

Applications

Mainly be used in the grinding and classification of inflammable, explosive and easily oxidized materials. 

Typical materials: carbonyl iron powder, red phosphorus, sulphur, phosphate, metal powder, NdFeB, RDX, cobalt powder etc.                                                                                                                                                                                                                                  

  Personalized design to solve the affairs on grinding and classification.
