Abstract

The invention provides a drum-based high-intensity magnetic machine for steel slag and a magnetic separation method. The machine comprises a case as well as a power input shaft and a roller which aremounted on the case, the power input shaft is fixedly connected with a driving drum, and an end part is connected with a speed adjusting motor; the roller is fixedly connected with a driven drum, a magnetic roll is mounted in the roller, and a composite magnetic system composed of a hard magnetic material is arranged on the magnetic roll; a belt surrounds the driving drum and the driven drum. Scrap iron in the steel slag is separated by magnetic overturn, magnetic stirring, gravity and centrifugal force, and the drum-based high-intensity magnetic machine and the magnetic separation method havethe advantages of being efficient, energy-saving, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the treatment of steel smelting slag, in particular to a steel slag drum belt magnetic separator and a magnetic separation method. Background technique [0002] The steel slag advanced treatment process CN108187880B, which the applicant has independent intellectual property rights, is based on the design principle of "more crushing and less grinding". According to the material characteristics of hot and stuffy steel slag, different crushing, screening and magnetic separation equipment are selected to implement "3 crushing + 3 stages of screening + 2 stages of magnetic separation + 1 stage of cleaning + 12 points of dedusting" cycle back and forth, not only economically and efficiently recover more than 99% of metals, but also standardize the particle size of export tailings to 0-5mm, the content of metal iron Below 1%. Magnetic separation equipment is the core equipment for iron selection, and its structure also needs to be de...
