With the development of economy, commercial concrete has become an important member in engineering construction, and it is developing towards the requirements of high-performance concrete and green concrete. Limestone powder is a kind of fine powder made by further grinding, which is made of stone chips produced during the production of limestone and mechanical sand as raw material. Through experiments and actual production applications,it is proved that limestone powder can greatly improve the workability of concrete, workability, and reduce the slump loss of concrete, improve mechanical property, increase slump without bleeding when limestone powder is used as concrete mineral admixture, especially when the specific fineness reaches 325 mesh. When applied to high strength concrete, the cohesiveness of concrete can be reduced and the fluidity of concrete can be improved.

Along with increasingly stringent environmental protection requirements of the state, desulfurization facilities need to be built in the existing new coal-fired power plants with sulfur content more than 1%. The desulfurization process of power plants mainly consists of limestone, lime gypsum wet process, accounting for 86% of the total capacity. However, the fineness of limestone powder requires that the pass rate of 325 mesh is more than 90% or 250 mesh is more than 95%.

In this situation, YUSHENG MACHINE has made a lot of technical improvements for the original vertical mill. Developed the large-scale limestone grinding equipment YSMT series limestone vertical mill. It has the characteristics of low energy consumption, large output and high fineness, which can meet the product requirements of different industries for limestone powder.

Limestone vertical mill combines the function of fine crushing, drying, grinding, powder classification and conveying. It has the characteristics of small land occupation, simple technical process, high grinding efficiency, low energy consumption, low noise, large drying capacity, easy adjustment of product fineness, no dust pollution, convenient maintenance, reliable operation, etc. Especially in the large-scale grinding technique, limestone vertical mill fully meets the needs of customers, and the main technologies and economic indicators have reached the international advanced level. It's widely used in large-scale material grinding and ultra-fine powder of metallurgy, electric power, cement, chemical industry, ceramics, non-metallic mines, power plant desulfurization, water slag, steel slag, mineral slag, coal, cement clinker, glass, quartz, limestone and other industries.
