Description

technical field [0001] The invention relates to the technical field of NdFeB processing, in particular to an NdFeB waste recovery device and a method for using it. Background technique [0002] NdFeB magnetic material, as the latest result of the development of rare earth permanent magnet materials, is widely used in the manufacture of permanent magnets. In the production process of NdFeB magnets, more waste materials are often produced, including cutting waste, sintered blanks, scraps, substandard products, severely oxidized powder, and heavily polluted cutting mud, etc., the total amount of which reaches the total investment. About 30% of the material. [0003] The recovery of NdFeB materials mainly includes multiple steps including roasting, acid dissolution, filtration and extraction. In order to ensure the treatment effect of these treatment processes, it is necessary to crush the waste residue before these processes. [0004] Before crushing or roasting, acid dissol...
