Efficient screening crushing device used for rare earth carbonate

Abstract

The invention relates to a screening crushing device, in particular to an efficient screening crushing device used for rare earth carbonate. In order to solve the technical problems, the invention provides the efficient screening crushing device used for rare earth carbonate. The efficient screening crushing device used for rare earth carbonate comprises a barrel body, a screening device, a crushing device, a crushing bin, a discharge tube, a charging hopper and the like, wherein the screening device is arranged above the barrel body; the crushing device is arranged above the screening device; the crushing device is arranged in the crushing bin; the bottom of the crushing bin is welded with a discharge tube; the discharge tube communicates with the crushing bin; the charging hopper is welded on the top of the crushing bin; and the charging hopper communicates with the crushing bin. The invention provides the efficient screening crushing device used for rare earth carbonate. The screening device is combined with the crushing device, so that efficient screening and crushing can be performed on rare earth carbonate.

Description

technical field [0001] The invention relates to a screening and crushing device, in particular to a high-efficiency screening and crushing device for rare earth carbonate. Background technique [0002] Rare earth has the reputation of "industrial vitamin", and 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. Lanthanide elements in the periodic table of chemical elements - lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, and...
