At present, China’s steel slag has a large amount of emissions and low utilization rate. The use of steel slag as a pavement base material can greatly reduce the exploitation of natural earth and stone materials, and has significant economic and social benefits. The graded steel slag and gravel are blended in a certain proportion to form a composite aggregate, which not only optimizes the grading of the steel slag, but also reduces the adverse effect of the hydration expansion of the steel slag on the stability of the aggregate body-level distribution. The composite aggregates were stabilized by different binders, and the ratio of the unconfined compressive strength was optimized. The ratio of the fly ash was directly stabilized and the cement fly ash was stabilized.
The Vertical Roller Mill developed by Shanghai SBM solves the technical problems of low output and high energy consumption of industrial mills, absorbs European advanced technology and combines Shanghai SBM’s many years of advanced mill design and manufacturing concepts and market demand. After years of painstaking design Improved large-scale grinding equipment.
The vertical roller mill integrates fine crushing, drying, grinding, powder selection and conveying. It has small floor space, simple process flow, high grinding efficiency, low energy consumption, low noise, large drying capacity and product fineness. Easy to adjust, no dust pollution, easy maintenance, reliable operation. Especially in the large-scale grinding process, it fully meets the needs of customers, and the main technical and economic indicators have reached the international advanced level. Widely used in metallurgy, electric power, cement, chemical, ceramics, non-metallic minerals, power plant desulfurization, water slag, slag, slag, coal, cement clinker, glass, quartz, limestone and other industries for large-scale material grinding and ultra-fine powder Grinding, grinding of steel slag blast furnace slag of special steel plant and power plant slag fly ash.
SBM has developed various types of mill equipment suitable for various materials, which can easily realize the adjustment of material fineness and output. The comprehensive performance of economical effectiveness is more suitable for the rational choice of small and medium investors while being applied by major industrial and mining enterprises.
