A precision crushing device for rare earth hot ore

Abstract

The invention provides an accurate crushing device for rare earth hot ore, and belongs to the field of crushing equipment. The accurate crushing device for rare earth hot ore comprises a preheating chamber, an ultrasonic chamber, an impact chamber, a primary breaking chamber, a fine crushing chamber and a screening device, wherein the preheating chamber, the ultrasonic chamber, the impact chamber,the primary breaking chamber and the fine crushing chamber are sequentially connected in sequence from left to right, and the screening device is arranged below a discharging port of the fine crushing chamber. According to the device, the ultrasonic chamber is arranged, so that the size of the rare earth ore can be preliminarily determined in advance, and particles with fixed sizes can be more easily formed in the subsequent impact and crushing processes; through the cooperation of the primary breaking chamber, the fine crushing chamber and the screening device, so that the control over the size consistency of ore particles is realized; the heat in the primary breaking process and the fine crushing process are recycled, so that the green treatment of the heat energy is realized; and the accurate crushing device has the advantages of being high in ore particle size consistency, low in pulverization rate, green and clean and the like.

Description

technical field [0001] The invention relates to the field of crushing equipment, in particular to a precise crushing device for rare earth hot ore. Background technique [0002] Rare earth ore needs to be crushed before smelting. The optimal effect of crushing is uniform particle size. However, the current crushing device first coarsely crushes rare earth ore and then crushes it. High, so it is necessary to go through operations such as powder re-agglomeration, which brings unnecessary excessive processes to production and increases production costs. If the uniformity of crushed ore can be greatly improved in the crushing stage, the above problems will be greatly improved. In order to improve the efficiency of the crushing process, the existing process will heat the minerals before crushing to form hot ore, and the hot ore will further generate heat due to friction during the crushing process. These excess heat will not only cause energy loss but also damage the If the equ...

Problems solved by technology

In order to improve the efficiency of the crushing process, the existing process will heat the minerals before crushing to form hot ore, and the hot ore will further generate heat due to friction during the crushing process. These excess heat will not only cause energy loss but also damage the If the equipment is damaged, if this part of the heat is used reasonably, it needs to be set reasonably.
