Abstract

The invention discloses a preprocessing device for neodymium, iron and boron waste materials before roasting, and mainly solves the problem that existing neodymium, iron and boron waste materials cannot be fully roasted and roasting efficiency is affected. The preprocessing device comprises a washing device, a breaking device, a centering device and a roasting device, wherein the washing device is provided with a left baffle plate, a right baffle plate, a front plate, a rear plate and a bottom plate; the right baffle plate is arranged on the right of the left baffle plate; the front plate isarranged in front of the left baffle plate and the right baffle plate; the rear plate is arranged behind the left baffle plate and the right baffle plate; the bottom plate is arranged on the bottom ofthe left baffle plate, the right baffle plate, the front plate and the rear plate; the breaking device is arranged in front of the washing device and is provided with a breaking box and a breaking reamer, wherein the breaking reamer is arranged in the breaking box and is used for breaking neodymium, iron and boron; the centering device is arranged between the breaking device and the washing device and is provided with a material blocking plate; the material blocking plate is arranged between the breaking box and the front plate; and the roasting device is arranged in front of the breaking device. The processing device has the advantages of being sufficient in roasting and high in roasting efficiency.

Description

technical field [0001] The invention relates to the field of NdFeB roasting technology, in particular to a pretreatment device for NdFeB waste before roasting. Background technique [0002] Rare earth elements are widely used in the manufacture of functional materials and are key elements for the development of high-tech industries. Some people believe that with the continuous development and utilization of rare earth elements, a new technological revolution will be triggered on a global scale. In the early days, due to the low level of rare earth element separation, purification, production and application, rare earth elements were only used as industrial "monosodium glutamate". materials", "magnetostrictive materials", "hydrogen storage alloy powder" and so on. As more and more rare earth elements are used, the recovery and reuse of non-renewable precious rare earth resources has become an important task for rare earth production enterprises. [0003] In the recycling pr...
