Special grinder for ndfeb
The material properties:
Neodymium magnet, also known as neodymium ferroboron magnet, is a tetragonal crystal system formed by neodymium, iron and boron (Nd2Fe14B).
If the powder is too fine, then the surface area in contact with oxygen is very large, and the spontaneous oxidation reaction will occur violently, so it will burn. Neodymium and iron in ndfeb oxidize spontaneously in the air.
The material used:
Ndfeb magnets are widely used in electronic products such as hard drives, mobile phones, earphones and battery-powered tools.
Equipment selection:
According to the flammable and oxidizing characteristics of materials, impact mill with inert gas protection is selected
The application type:
A series of 【ZJ-DBC】
The process flow:
The working principle of:
What ZJ had series of inert gas protection crushing classifier is of easy oxidation of inflammable, explosive, the materials are crushed, add an inert gas (nitrogen, argon, carbon dioxide, etc.) as a medium to achieve closed-circuit circulation, nitrogen compression system, nitrogen gas filtration system, crushing, grading systems, collecting system, processing and unloading system, nitrogen purity test complement system, nitrogen generating system and electric control system composition. It is widely used in the processing of metal powders, easily oxidized materials and inflammable and explosive materials.
Characteristics of the equipment:
1. It can process materials with mohs hardness level 1-10, and can mix and crush several kinds of materials.
2, isolation of oxygen, according to the characteristics of processed products to choose the purity of inert gas, and achieve full closed cycle use of inert gas, small loss, reduce the cost.
3. The oxygen content in the process can be accurately monitored, and the oxygen content in the system can be controlled up to less than 1PPM as required. Realize automatic nitrogen and other inert gases to maintain the pressure balance, so that its oxygen content always maintain within the safety production standards.
4. The material is added at a constant speed, and the bending Angle of the inlet and outlet material pipeline of the equipment and the shape of each component are all calculated scientifically. There is no dead Angle, and the powder will not accumulate in the pipeline.
5. The cooling device is installed on the operation pipeline to reduce the potential safety hazard of the equipment under long working hours or high temperature environment.
6. The whole system is equipped with explosion-proof holes in the pipeline, which can reduce the loss to ***** when the explosion and explosion are caused by excessive pressure and concentration in the system.
Full seal negative pressure operation, pulse automatic ash removal, imported high-precision filter material, high dust collection efficiency.
8. The whole system adopts automatic control, which can realize one-key start and stop, simple and convenient operation and connection with central control can realize remote control.
