Method and system for the manufacturing of raw material for production of rare earth magnets

A method and a plant for the production of a powdery material, which is provided for the manufacturing of rare earth magnets are provided. First of all, at least one magnetic or magnetizable raw material, respectively, is provided and is comminuted into a powdery intermediate product, which includes powder particles including corners and edges, by means of conventional comminuting methods. The sharp-edged powder particles are chamfered subsequently. The optimized powdery product including the chamfered powder particles is used for the manufacturing of rare earth magnets. 本发明涉及用于制造粉末状的且生产稀土磁铁的材料的方法和设备。首先，提供至少一种磁的或可磁化的原料，并且借助传统的粉碎方法粉碎成粉末状的中间产品，中间产品包括具有角部和棱边的粉粒。然后使尖锐棱边的粉粒倒圆。包括经倒圆的粉粒的经优化的粉末状产品用于生产稀土磁铁。
