New Technology of Steel Slag Utilization

In recent years, there is a kind of new technology in steel slag comprehensive utilization--to utilize the slag after crushing, drying, sieving, grinding and pelletizing. In this way, the steel slag can be fully utilized without any waste, it solve the problem of land occupation and environmental pollution of steel slag. It will also bring large benefit for the society and economy. For Wuhan Iron & Steel Corp, it needs 81.74 million RMB as investment to deal with all the steel slag, and it will bring 36.36 million RMB profit per year and save up space.

For the steel slag contains more iron, the treatment process has some difference with mineral slag. Through years of R&D, Guilin Hongcheng developed the most suitable technology for steel slag processing.

HLM Series Vertical Mill is a kind of advanced mill developed by Hongcheng based on two decades of R&D experience and introduction of foreign advanced technology. It features in a combination of drying, grinding, classifying and conveying. Hongcheng HLM Vertical Mill has the following advantages: efficient grinding, lower power consumption, larger feeding size, adjustable fineness, simple process flow, space-saving, lower noise, no air pollution, easy maintenance, lower operation cost, longer working life of wearing parts, etc. HLM Vertical Mill is widely applied in power, metallurgical, cement, chemical and non-metal industry, such as cement raw material, slag powder, manganese, gypsum, coal, barite, calcite, bauxite, etc.

The HLM Vertical Mill widely applied in steel slag, grain slag and mineral slag powder processing, brought large benefit for the society and economy.
