Under normal circumstances, the particle size is 150 ~ 500 \u0026 mu; the iron powder composed of particles within the range of M is coarse powder, the particle size is 44 ~ 150 \u0026 mu; ; M is extremely fine powder, less than 0.5 \u0026 mu; M is an ultra -fine powder. Generally, the granularity of the 325 target sieve is less than 44 \u0026 mu; the powder of M is called sub -sieve powder. If a higher accuracy of screening is required, it can only be crushed with airflow. Can be done with JZDF inert gas to protect the airflow crushing classifier. Let's introduce the processing process of iron powder.
When the inert gas protection airflow crushing classifier is to add inert gas (nitrogen gas to flammable, explosive and oxidized materials, , Glutter, carbon dioxide, etc.) as a medium to achieve closed circular loop crushing, by nitrogen compression system, nitrogen filtering system, crushing system, hierarchical system, collecting system, addition, unloading system, nitrogen purity test supplementary system, nitrogen -making system, electrical electrical power Control system composition. It is widely used in metal powder, easy oxidation raw materials and flammable and explosive materials. Features of inert gas protection air flow crushing grading machine features: 1. Materials that can be processed by Mohl Hardness 1-10, can be mixed with several materials. 2. Isolation of oxygen, the characteristics of the root of the root process require the purity of the inert gas, and realize the inert gas of the fully enclosed cycles, which is small and reduces the cost. 3. During the processing process, the oxygen amount can be monitored accurately, and the oxygen content in the system is controlled according to the need, which can reach less than 1ppm. Realize the pressure balance of inert gas such as nitrogen supplement, so that its oxygen content is always kept within the safety production standard. 4. The material is added at a constant speed. The bending angle of the inlet and outlet pipelines and the shape of each component are scientifically calculated. Without dead ends, the powder will not accumulate in the pipeline. 5. The cooling device is installed on the running pipeline to reduce the safety hazards of the equipment for a long time or under the high temperature environment. 6. The whole system has explosion -proof holes on the pipeline. It reduces the loss to the ZUI low when the internal pressure and concentration of the system exceed the standard. 7. Fully sealed negative pressure operation, the pulse automatically cleans the ash, imports high -precision filter materials, and the dust collection efficiency is high. 8. The entire system adopts automated control to achieve one -button start and stop. The operation is simple and convenient to connect with the central control to achieve remote control. The inert gas protection airflow crushing classifier is one of the main equipment of Qingdao Youmingke. It has been widely used in many areas and has been highly praised by users. Free experimental detection can be provided.
