Abstract

The present invention relates to the technical field of steel slag recovery, especially a steel slag resource recovery and screening system for steel production. Aiming at the problem that the steel slag recovery system in the prior art is inconvenient to pour the weighed material into the stirring device, the following scheme is proposed , which includes a crushing system, a feeding system, a magnetic separator, a preheating system, a grinding system, a calcination device, a screening system, a weighing system and a stirring system, wherein the feeding system is used to crush the crushing system The finished materials are input into the magnetic separator for screening, the preheating system is used to heat the tailings screened by the magnetic separator, the grinding system is used to grind the heated tailings, and the calciner is used to calcinate the ground tailings . The invention has reasonable structure and simple operation, can reasonably recycle steel slag resources, and greatly simplifies the process of material weighing and stirring in the process of reclaiming steel slag, thereby improving production efficiency and being easy to popularize and use.

Description

technical field [0001] The invention relates to the field of steel slag recovery, in particular to a steel slag resource recovery and screening system for steel production. Background technique [0002] Steel slag mainly comes from the oxides formed after the oxidation of elements contained in molten iron and scrap steel, impurities brought by metal furnace charges, slagging agents added such as limestone, fluorite, silica, etc., as well as oxidants, desulfurization products and eroded furnace lining materials Wait. The main way to utilize steel slag in my country is to recycle it within steel companies, replace lime as a solvent, and return it to blast furnaces or sintering furnaces as raw materials for ironmaking. [0003] The recycling system used to process steel slag in the prior art involves a stirring process, which is used to mix steel slag with other additives to obtain the final product, but when adding other materials, it needs to be quantified according to the a...
