Rare earth crushing device

Abstract

The invention discloses a rare earth crushing device, and in particular relates to the technical field of rare earth permanent magnet element manufacturing. The rare earth crushing device comprises acrushing box; a motor is arranged at the top of the crushing box; a rotating shaft is arranged at the bottom of the motor; a first crushing cutter is fixedly arranged on the rotating shaft; a first screening plate is arranged at the bottom of the first crushing cutter; a second crushing cutter is arranged at the bottom of the first screening plate; a second screening plate is arranged at the bottom of the second crushing cutter; a third crushing cutter is arranged at the bottom of the second screening plate; a third screening plate is arranged at the bottom of the third crushing cutter; a drawer is arranged at the bottom of the third screening plate; and two feed ports are formed in the top of the crushing box. Three different screening plates are arranged in the crushing box for screeningrare earth, and three crushing cutters are used for crushing each layer of screened rare earth, so that the crushing efficiency is improved, and meanwhile, the secondary crushing of the rare earth iseffectively prevented to save rare earth resources.

Description

technical field [0001] The invention relates to the technical field of rare earth permanent magnet element manufacturing, and more specifically, the invention relates to a rare earth crushing device. Background technique [0002] Rare Earth (Rare Earth) is the general name of seventeen metal elements including lanthanides, scandium and yttrium in the chemical periodic table. Due to their special atomic structure, the members of the rare earth family are very lively, and all of them have extraordinary skills and boundless magic power. Combining them with other elements can form a wide variety of new materials with ever-changing functions and different uses, and their performance is doubled. They are called contemporary "industrial monosodium glutamate". It is not possible to keep the original magnetic state without changing forever, but its magnetism is relatively stable, and the decay period is relatively long. The production process of permanent magnet components that have ...

Combining them with other elements can form a wide variety of new materials with ever-changing functions and different uses, and their performance is doubled. They are called contemporary "industrial monosodium glutamate". It is not possible to keep the original magnetic state without changing forever, but its magnetism is relatively stable, and the decay period is relatively long. The production process of permanent magnet components that have appeared on the market cannot do without rare earths, but rare earths need to be used before they can be used. crush it first

[0003] In the prior art, traditional methods such as direct rolling are mostly used for rare earth crushing, which not only takes a long time to operate, but also often carries out secondary crushing of some rare earths that meet the specifications, resulting in waste of rare earths, and the rare earths cannot be crushed. Therefore, it is necessary to invent a rare earth crushing device to solve the above problems
