Discharging device of ball mill

Abstract

The invention belongs to the technical field of metallurgy, and particularly relates to a discharging device of a ball mill. The discharging device of the ball mill comprises a discharging pool, a slurry pump, a discharging pipe, a material collecting hopper, a valve component, a material uniformizing groove, a material dispersing cover, vibrating screens, a coarse material recycling pool, a feeding hopper, a feeding pipe and a fine material receiving pool. According to the discharging device of the ball mill, discharged materials of the ball mill can be screened through the vibrating screens,screened coarse materials are directly discharged into the ball mill again through dead weight, and therefore, automatic circulating ore grinding is achieved, back-and-forth conveying is not needed,manpower input is small, and the ore grinding efficiency is high. The discharging device of the ball mill has the advantages that an iron removal device is arranged, so that the content of small steelball fragments in the back-milled coarse mineral aggregate is effectively reduced, and abrasion of the small steel ball fragments to the side wall of a ball mill material cavity and the slurry pump is reduced. As the material uniformizing table is arranged, slag slurry discharged from a slag slurry outlet can be evenly distributed to two outlets and screened through the corresponding vibrating screens, so that the screening efficiency is improved; and moreover, the slag slurry amount of each vibrating screen is reduced in a flow dividing mode, so that the screening effect is better.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a discharge device for a ball mill. Background technique [0002] After the ore is crushed, it needs to be ground in the ball mill, and then it needs to be concentrated, flotation and other beneficiation processes. In the prior art, the slurry discharged from the ball mill is basically transported to the designated screening area for screening. Coarse material needs to be transported back to the ball mill for grinding, the process of transporting back and forth is cumbersome, the manpower input is large, and the loss of mineral material is serious during the transport process. Contents of the invention [0003] The object of the present invention is to provide a ball mill discharge device, which can screen the ball mill discharge, and automatically discharge the screened coarse material directly into the ball mill to realize automatic circular grinding without th...
