Abstract

The invention relates to the technical field of steel slag processing in metallurgical industry, and discloses a stainless steel slag drying and air separation device and a drying and air separation method. The stainless steel slag drying and air separation device comprises a hopper, a bar screen, a bucket elevator, a drying kiln, a cyclone dust collector and a bag dust collector, the drying kiln is internally provided with a lifting plate, a combustion fan and an air blower, the bottom end of the drying kiln is provided with an aggregate outlet, and the upper part of a material outlet of the drying kiln is provided with a powder outlet. The stainless steel slag drying and air separation device integrates drying and air separation in a whole, after preliminary screening of a stainless steel slag raw material, the stainless steel slag is dried and by the drying kiln, meanwhile the air separation is performed, metal-containing material enrichment is facilitated, powder with smaller particle size is collected by the cyclone dust collector, and the bag dust collector can prevent the dust from discharging into the atmosphere; the device wear caused by the stainless steel slag can be reduced, the device service life can be prolonged, production cost can be reduced, wet processing water consumption and water treatment cost can be reduced, and energy saving and emission reduction can be achieved.

Description

technical field [0001] The invention relates to the technical field of steel slag treatment in the metallurgical industry, in particular to a stainless steel slag drying and winnowing device and a drying and winnowing method thereof. Background technique [0002] Steel slag is industrial solid waste slag produced in the process of smelting steel. The waste slag produced by steel mills can be divided into two types due to different cooling processes: dry slag and water slag. Generally speaking, there are three components in steel slag: steel grain, iron powder and waste ash. Selecting the steel grain and iron powder through a reasonable process can produce huge economic benefits. [0003] First, the steel slag needs to be ground to break the structure between them and separate them. The equipment used to grind steel slag is ball mill, rod mill, etc. [0004] Domestic metallurgical enterprises usually use wet treatment for stainless steel slag. First, the steel slag is evenl...
