Lime Plant Vertical Grinding Mill 56-80t/h HVM Limestone Vertical Grinding Mill Energy Saving
Description
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 made of stone chips produced during the production of limestone and machine-made sand as raw materials, and is further ground into fine powder.
Through experiments and practical production applications, it is confirmed that when limestone powder is used as concrete mineral admixture, especially when the specific fineness reaches 325 mesh, limestone powder can greatly improve the workability and workability of concrete, reduce concrete slump loss, improve mechanical properties, Increase the slump without bleeding. When applied to high-strength concrete, it can reduce the cohesion of concrete and improve the fluidity of concrete.
With the increasingly strict requirements for environmental protection in China and the world, the desulfurization facilities are being built in newly built power plants with coal-fired sulfur content greater than 1%. 86% of the total capacity. The fineness of limestone powder requires a pass rate of more than 90% for 325 mesh or more than 95% for 250 mesh.
Under this situation, our company has made a lot of technical improvements to the original vertical mill. Developed a large-scale limestone grinding equipment HVM limestone vertical mill. It has the characteristics of low energy consumption, large output and high product fineness, which can meet the product requirements of different industries for limestone powder.
