The invention discloses an automatic ball adding system of a ball mill and belongs to the technical field of ore grinding. The automatic ball feeding system is characterized in that a conveying deviceis arranged below a ball outlet of a ball storage bin, ball inlets of a plurality of ball adding machines are formed below a ball outlet end of the conveying device, the ball mill is arranged below aball outlet of the corresponding ball adding machine, a hopper is fixedly arranged on a base, a ball inlet of a hopper is arranged below the ball outlet end of the conveying device, a ball unloadingbarrel is rotatably arranged at the ball outlet of the hopper, a ball inlet of the ball unloading barrel is communicated with a ball outlet of the hopper, and a sealing plate is fixedly arranged at the ball outlet of the ball unloading barrel. The system is advantaged in that labor intensity can be reduced, manpower and material resources can be saved, the density of one-time ball adding can be reduced, reactive abrasion between balls can be reduced, rationality of the steel ball proportion in the mill is improved, and ore grinding efficiency of the mill is improved.
Description
technical field [0001] The invention relates to the technical field of ore grinding, in particular to an automatic ball adding system for a ball mill. Background technique [0002] The ore grinding process is an important part of the metal ore beneficiation process. The ball mill is the main equipment in the grinding process. Steel balls are added to the ball mill as the grinding medium to throw, squeeze, grind and strip the ore in the mill. smash. Reasonable steel ball filling rate and ball diameter ratio can not only improve the grinding efficiency of the mill, but also help reduce ball consumption. [0003] With the discovery trend of large-scale mineral processing equipment, more and more large-scale ball mills are installed in the grinding industry, and the amount of steel balls that need to be replenished is as many as ten tons or even dozens of tons every day. However, in the prior art, the way of adding balls to the ball mill is to add balls manually every day, whi...
