Abstract

The invention relates to a rare-earth ore crushing and sieving device which comprises a crushing transport chamber, a solid-liquid separation chamber, a drying preheating chamber, an ore powder temporary storage box, a sewage filtering chamber and a water circulation system. Through special arrangement for all the parts, especially arrangement of the sewage filtering chamber, the water circulatingsystem and the drying preheating chamber, in the rare-earth ore crushing process, water resources can be recycled, heat quantity can achieve maximized comprehensive utilization, and the environmentalfriendliness of the crushing process is strengthened.

Description

technical field [0001] The invention belongs to the field of rare earth ore processing devices, in particular to a rare earth ore crushing and screening device. Background technique [0002] After the rare earth ore is mined, it needs to be crushed to break the large rare earth ore into very fine ore particles, and then carry out the wet or fire extraction process of the rare earth ore after corresponding treatment. At present, the crushing of rare earth ores is divided into coarse crushing and fine crushing (also called pre-crushing and crushing) and other steps. In the current crushing process, a certain amount of sewage is produced and a large amount of heat input is required. The sewage needs additional treatment, and the heat is not effectively recovered at present, so the environmental friendliness is not very high. Contents of the invention [0003] The present invention proposes a rare earth ore crushing and screening device. [0004] It is achieved through the ...
