Novel sieving and crushing device for rare earth carbonate

Abstract

The invention relates to a sieving and crushing device, and particularly relates to a novel sieving and crushing device for rare earth carbonate. The technical problem to be solved by the invention is to provide a novel sieving and crushing device for rare earth carbonate. In order to solve the technical problem, the invention provides a novel sieving and crushing device for rare earth carbonate. The novel sieving and crushing device for the rare earth carbonate comprises a cylinder body, a charge device, a left-right swing device, a hopper, a fixed plate, a connection rod and the like, wherein the left-right swing device is arranged below the cylinder body; the hopper is formed above the charge device; the fixed plate is arranged below the charge device; the left end of the fixed plate is connected with the upper end of the right sidewall of the connection rod in a welding manner; and the lower end of the connection rod is connected with the top of a base I in a welding manner. The novel sieving and crushing device for the rare earth carbonate adopts a simple split structure, is easy to repair and maintain, greatly increases the sieving and crushing efficiency of the rare earth carbonate through the combination of the charge device and the left-right swing device, and is good in sieving and crushing effect, capable of saving enterprise resources, convenient to operate, and easy to produce and manufacture.

Description

technical field [0001] The invention relates to a screening and crushing device, in particular to a novel screening and crushing device for rare earth carbonate. Background technique [0002] Rare earths are integral to the manufacture of everything from precision-guided weapons known as "smart bombs" to radar and night-vision goggles. Because of its low natural abundance and the symbiotic form of oxides or oxo-salt minerals, it is called "rare earth". The term rare earth is a name left over from history. Rare earth elements have been discovered since the end of the 18th century. At that time, people often called the solid oxides insoluble in water as soil. Rare earths are generally separated in the form of oxides. Although the reserves on the earth are very large, it is difficult to smelt and purify them, so they are relatively rare, so they are named rare earths. Generally speaking, rare earths on earth exist in the form of rare earth oxides. Rare earth element oxides ...
