Abstract

The invention discloses a permanent magnetic ferrite waste recycling process, which comprises the steps of 1, feeding waste magnetic shoes into a crusher, crushing the waste magnetic shoes to 4 microns through continuous crushing, feeding a permanent magnetic ferrite pre-sintered material, an additive and the crushed waste magnetic shoes into a mixing device, and adding the additive for mixing, thereby obtaining a mixture; and 2, placing the mixture in a kiln at the moment, and sintering for 2-3 h at the temperature of 1260-1320 DEG C, and meanwhile, introducing sufficient oxygen into the kilntill a 95% ferrite material is generated. A fixing frame is arranged on a supporting frame, a material mixing barrel can be driven to turn over through the meshing relation between a driving gear ona servo motor and a rotating gear so as to mix the materials, meanwhile, a stirring motor is used for turning over and stirring the materials in the material mixing barrel, and the mixing speed of thematerials is further increased.

Description

Technical field[0001]The invention relates to the technical field of permanent ferrite, in particular to a process for recycling permanent ferrite waste.Background technique[0002]Because of its low price and good magnetic properties, permanent magnet ferrite has high resistivity and belongs to the semiconductor type, so it has small eddy current loss and large coercive force, and can be effectively used in large gap magnetic circuits. Among them, it occupies a pivotal position in the field of magnetic materials and has a wide range of applications. It does not contain precious metals such as nickel and cobalt. It has abundant raw materials, uncomplicated process and low cost, and can replace Al-Ni-Co permanent magnets. Its maximum magnetic energy product (B+H)m is low, so under the same magnetic energy, it is larger than metal magnets. In the production process, waste magnet tiles are usually produced, which will affect its own magnetism.[0003]The Chinese patent discloses a method f...
