Limestone Grinding Mill Clinker Pulverizer Vertical Roller Mill for Limestone
Description:
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 more and more countries, desulfurization facilities are built in the existing 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 factory has made a lot of technical improvements for the original vertical mill. Developed a large-scale limestone grinding equipment HVM vertical limestone grinding. 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.
【Application field】
Limestone grinding station, thermal power plant, commercial concrete station and other industries.
【Characteristics】
1. Change the speed ratio of the original reducer, adjust the speed of the reducer for different raw materials through the frequency converter, and improve the grinding efficiency of the mill.
2. Change from two rollers to three rollers, without changing the general frame of the original mill, change the two rollers of the mill into three rollers, increase the grinding area of the mill and increase the output of the mill.
3. The straight blade is changed to "Z" blade. By changing the shape and quantity of the original dynamic and static combined separator, the product fineness can reach 325 mesh and the pass rate is more than 90%, the output is increased by 10%, and the energy consumption is reduced by 15%.
4. Reasonable system configuration, reduce investment in supporting equipment, and reduce system power consumption.
