A preliminary magnetic separation device for rare earth crushing

Abstract

The invention relates to a magnetic separation device, in particular to a preliminary magnetic separation device for rare earth crushing. Provided is a rare earth crushing preliminary magnetic separation device that can effectively extract iron ore concentrate particles from rare earth, prevent obstacles from entering a magnetic separator to interfere with normal operation, and is easy to operate and maintain. Provided is such a preliminary magnetic separation device for rare earth crushing, comprising: pillars, four pillars are provided with a worktable on the top, and a discharge pipe is provided on one side of the bottom of the worktable; There is a crushing mechanism; a magnetic separation mechanism, and a magnetic separation mechanism is provided on the top of the worktable near the side of the discharge pipe. The two rollers rotate in opposite directions to shred the rare earth block, the scraper moves to scrape the large particles of the minced rare earth block from the worktable, and the minced small particles slide down to the bottom of the drum through the scraper, and the magnetic rod adsorbs the rare earth. On the outer wall of the drum and rotate synchronously with the drum, the remaining ore particles fall out from the discharge pipe, and then extract the iron ore concentrate particles.

Description

technical field [0001] The invention relates to a magnetic separation device, in particular to a preliminary magnetic separation device for rare earth crushing. Background technique [0002] The term rare earth is a name left over from history. Rare earth elements have been discovered one after another since the end of the 18th century. At that time, people often called the solid oxide insoluble in water as soil. , hence the name rare earth. [0003] Most rare earth metals are paramagnetic. During the preparation and processing of various materials, adding rare earth elements can significantly improve the performance and preparation process of products. At present, rare earth permanent magnet materials are known to have the best comprehensive performance. , which is superior to ferrite and AlNiCo. In addition, rare earth materials are also widely used in the fields of luminescence, hydrogen storage, superconducting materials, and military and agricultural fields. [0004]...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the disadvantages that the inside of the magnetic separator is easy to enter obstacles when the magnetic separator is in use, the lighter ones will scratch the cylinder skin, and the heavier ones will jam the cylinder or scratch the cylinder skin, making it difficult to maintain. The technical problem is: to provide a Rare earth crushing preliminary magnetic separation device that effectively extracts iron concentrate particles, prevents obstacles from entering the magnetic separator to interfere with normal operations, and is easy to operate and maintain
