Problems solved by technology

[0003] A large amount of dust will be generated in the process of ore crushing and the process of feeding materials for crushing. If it is not treated, it will seriously endanger the health of the personnel on the job site, pollute the working environment of the site, and the ash falling will also cause the operation of other mechanical equipment in the site to be blocked. In addition, in the Dust must be removed before entering the next process to improve the purity of the ore

Abstract

The invention discloses an ore crushing dedusting system, which mainly comprises a base, a conveyer, a dedusting room, a crusher, a sprinkler, a feed inlet, a discharge outlet, a water collection tank, a wastewater tank, and a clean water tank, wherein the dedusting room is fixed on the base and arranged over the conveyer, the crusher and the sprinkler are arranged in the dedusting room, the feedinlet and the discharge outlet are arranged at both ends of the dedusting room, the water collection tank is arranged at the lower part of the conveyer, a blocking plate is horizontally arranged in the middle of the dedusting room, through holes are evenly distributed in the blocking plate, a baffle is vertically arranged in the dedusting room, a certain gap is reserved between the blocking plateand the baffle, the blocking plate and the baffle divide the dedusting room into a first dedusting chamber, a second dedusting chamber and a third dedusting chamber, the second dedusting chamber is provided with a circulating return pipe, and the third dedusting chamber is provided with a draft pipe. Adopting a three-stage dedusting mode integrated with closed dedusting and wet dedusting, the dedusting system can realize a high dust recovery rate and a low dust escape rate during ore crushing, thus improving the operating environment of an ore crushing site and improving the health of operating personnel.

Description

technical field [0001] The invention belongs to the field of mining technical equipment, in particular to an ore crushing and dust removal device. Background technique [0002] In the mining process of the mine, the ore needs to be crushed, refined, screened and other operations, and the crushing is undoubtedly the first step in the whole process. Particularly important. [0003] A large amount of dust will be generated in the process of ore crushing and the process of feeding materials for crushing. If it is not treated, it will seriously endanger the health of the personnel on the job site, pollute the working environment of the site, and the ash falling will also cause the operation of other mechanical equipment in the site to be blocked. In addition, in the Dust must be removed before entering the next process in order to improve the purity of the ore. Contents of the invention [0004] The object of the present invention is to provide an ore crushing and dust remova...
