Advantages of producing cement from waste steel slag in steel mills

After the steel slag reaches the raw material workshop, it enters the processing line through the feeding system, and then is repeatedly vibrated, screened and purified on the processing line hundreds of meters long. After the magnetic materials containing metal are screened out step by step, all of them will be returned to the steel plant.

It is reported that the annual output of various solid wastes in Baowu Qingshan Base exceeds 8 million tons. Jinzi Company participates in the solid waste recycling and processing and utilization of the whole process. The iron-containing wastes are basically “recycled” as soon as they are “born”. During the treatment process, 4 sets of dust removal systems and spray devices were arranged along the line to control the dust emission per standard cubic meter within 10 mg, meeting the national standard requirements.

Even the steel slag and slag tailings that do not have the value of “returning to the furnace” can be used as the main raw material of high-grade cement to be applied to various projects, which can not only reduce the cost of the project, but also reduce the trouble of soil remediation, with significant economic benefits. At the same time, it saves the energy consumed in the production of cement, reduces the pollution discharge, and has good ecological benefits.
