Abstract: Изобретение относится к способу получения исходного материала для изготовления редкоземельного магнита, а также к установке для получения исходного материала для изготовления редкоземельных магнитов. Сначала подготавливают по меньшей мере один магнитный, соответственно намагничивающийся сырьевой материал и измельчают его традиционными методами измельчения в порошкообразный промежуточный продукт, который состоит из частиц с углами и краями. Затем имеющие острые края частицы округляют. Причем образующиеся в результате этого округленные частицы порошкообразного промежуточного продукта имеют такой же размер, что и ребристые частицы порошкообразного промежуточного продукта. Причем они имеют размер примерно от 2 до 10 мкм, преимущественно от 3 до 5 мкм. Полученный оптимизированный порошкообразный продукт, состоящий из округленных частиц, используют для изготовления редкоземельных магнитов. Изобретение позволяет значительно уменьшать и/или ограничивать количество острых углов и краев у частиц порошка в порошкообразном промежуточном продукте и получать тем самым оптимизированный исходный материал для изготовления редкоземельных магнитов более высокого качества. 2 н. и 9 з.п. ф-лы, 6 ил.
