Hongcheng vertical mill can efficiently recycle and utilize steel slag

    Slag is mainly composed of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus oxides, is a very important product during metallurgical process and the content of the dominant position product; is normally been abandoned in the past due to the not mutual tech of recycling. But slag contains many useful minerals and trace elements; therefore, it can be carried out comprehensive development and utilization, expanding the resource utilization of steel slag. Study shows that the waste slag can replace natural stone to create low noise and wear-resistant road surfaces.

    Steel slag is clinker in remelting phase with low melting temperature. Re-melting liquid phase is formed early with good liquidity. There are two main ways of slag utilization as a secondary resource, first is used as a solvent recycling in smelting factory which not only can replace limestone but also can recovered iron and other useful elements from a large amount of metallic. So to improve the integrated steel slag utilization is a benefit to people.

    Statistic shows that slag is one of the main industrial solid waste in China, the annual production of over 100 million tons, the total accumulation of more than 700 million tons, utilization rate is only about 30%. Natural stone is a non-renewable resources, the massive exploitation for road construction has caused serious damage to ecological environment. Slag Road has many advantages such as high strength, wear resistance and slip resistance, and low maintenance costs. Waste slag instead of natural stone, to mixed with concrete and asphalt can repair the damaged road surface.

    A complete production line in the recycling of steel slag not only including the slag milling machines and other major equipment, but also including shredders, feeders, conveyors and other equipment. Guilin Hong Cheng specializes in producing all kinds of mill equipment; we are committed to provide complete solutions for customers. For sure customers can also selecting different devices used in conjunction to achieve high efficiency purposes according to their actual needs.

    Hong Cheng HLM vertical mill can self-integrate crushing, drying, grinding, conveying in one system, the process is simple, less equipment system, compact structure, small footprint which is only 50% of the ball mill, open layout available, construction costs is low, directly reduce the cost of business investment, especially the mill adapt new roller sealing device which is more reliable for industrial solid waste and without blower sealed, further reducing the oxygen content within the mill, explosion suppression is more excellent.
