METHOD AND EQUIPMENT FOR PRODUCING POWDER OF NEODYMIUM-IRON-BORON RARE-EARTH PERMANENT MAGNETIC ALLOY |
摘要 |
PROBLEM TO BE SOLVED: To provide a method and equipment for producing powder of neodymium-iron-boron rare-earth permanent magnetic alloy.SOLUTION: The method for producing powder of neodymium-iron-boron rare-earth permanent magnetic alloy comprises: providing hydrogen-pulverized powder after being subjected to material mixing into a hopper of a material feeder; feeding the mixed powder into a grinding chamber through the feeder; grinding the mixed powder via high-speed gas flow ejected by a nozzle; sending the ground powder into a centrifugal powder separator by airflow so as to sort the powder; sending fine powder into a cyclone collector by a separator for collection, and collecting a small quantity of fine powder discharged along with the airflow of a vent pipe of the cyclone collector, again by a rear cyclone collector; sending the powders collected by the cyclone collector and the rear cyclone collector into a material-collecting tank through a material collector; and sending the gas discharged from the rear cyclone collector into an intake pipe of a nozzle for cycle use, after being compressed by a compressor and cooled by a cooler. |
