Airflow mill

The airflow mill contains airflow crushing chamber, feeding mechanism, nitrogen supply mechanism and a magnetic particle trapping mechanism and the airflow crushing chamber communicated, magnetic particle trapping mechanism for filtering cyclone cyclone, filter integrates collector. In the air flow crushing chamber is arranged at the bottom of the valve. Connected with the exhaust port is provided with a milling machine vacuum pump. The utility model is based on the existing of neodymium iron boron permanent magnetic material with improved airflow pulverizing mill, milling machine overcomes the defects of the existing shortcomings, presents a milling machine milling technology can meet the requirements of high performance NdFeB permanent magnets. Magnetic particle size distribution curve of the output of the sharp, size distribution curve is reasonable, the final output of neodymium iron boron magnet with high performance. Easy to use, saving nitrogen.
