Method for reducing fine powder rate of titanium residue breaking

Abstract

The invention discloses a method for reducing the fine powder rate of titanium residue breaking, and belongs to the field of titanium residue breaking treatment. The method comprises three steps of primary breaking sieving, jaw brushing sieving and ball milling sieving, wherein finished titanium residue and small-block titanium residue are obtained by the primary breaking sieving, the small-blocktitanium residue is broken into finished titanium residue and large-particle titanium residue by the jaw brushing sieving, and finally the large-particle titanium residue is subjected to grinding sieving by a double-layer sieve mesh type ball mill to obtain more than 95% of the finished titanium residue. According to the present invention, through the comprehensive utilization of the multi-stage fine-breaking sieving and the double-layer sieve mesh type ball mill, the repeated breaking of the fine-particle titanium residue is avoided, the 200 mesh titanium residue content is effectively reduced, the requirements of the subsequent processing on the particle size of the titanium residue are met, the yield of the titanium residue is improved, and the waste of resources is reduced.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to the field of titanium slag crushing and treatment. Background technique [0002] At present, there are two mainstream methods of titanium slag crushing, one is primary crushing (mechanical or falling ball, etc.) + jaw crusher + hammer crushing, mainly by adjusting the speed, the distance between the discharge ports, and the distance between the hammer head and the impact plate. The particle size is controlled by other methods, the control accuracy is poor and the particle size fluctuates greatly with mechanical wear; the second is primary crushing (mechanical or falling balls, etc.) + jaw crusher + ball mill, by adjusting the speed of the ball mill, filling rate, and the ratio of large and small balls The disadvantage of this method is that the content of the fine particle grade (-200 mesh) is unstable and the particle size fluctuates greatly with mechanical wear, that is,...
