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.

Re:The data based on Mohs'hardness 3-4 material
Limestone Bond Index≤13kwh/t
【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. Reasonable system configuration, reduce the investment in
supporting equipment, and reduce the power consumption of the
system.
