SHMX limestone vertical mill
【Equipment Overview】:
With the development of the economy, commercial concrete has become an important component in engineering construction and is developing towards the requirements of high-performance concrete and green concrete. Limestone powder is made from stone chips generated during the production of limestone and machine-made sand, and further ground into fine powder. Through experiments and practical production applications, it has been confirmed that when limestone powder is used as a mineral admixture for concrete, especially when the fineness reaches 325 mesh, it can greatly improve the workability and workability of concrete, reduce the loss of concrete slump, improve mechanical properties, increase slump without bleeding. When applied to high-strength concrete, it can reduce the cohesiveness of concrete and improve its flowability.
With the increasingly strict environmental protection requirements of the country, existing newly built coal-fired power plants with sulfur content greater than 1% are constructing desulfurization facilities. The desulfurization process of power plants mainly uses limestone and lime gypsum wet process, accounting for about 86% of the total capacity. The fineness of limestone powder is required to be above 90% of 325 mesh or above 95% of 250 mesh.
In this situation, our factory has made significant technological improvements to the original vertical mill. Developed SHMX limestone vertical mill, a large-scale limestone powder grinding equipment. It has the characteristics of low energy consumption, large output, and high product fineness, meeting the product requirements of different industries for limestone powder.
【 Application Fields 】:
Industries such as limestone grinding plants, thermal power plants, and commercial concrete stations.
【Performance Characteristics】
1. Change the original speed ratio of the reducer and adjust the speed of the reducer according to different raw materials through a frequency converter to improve the grinding efficiency of the mill.
2. Change from two rollers to three rollers. Without changing the general framework of the original mill, the two rollers of the mill will be changed to three rollers to increase the grinding area and increase the output of the mill.
3. The straight blades are changed to "Z" blades, and by modifying the shape and quantity of the original dynamic and static separator, the product fineness can reach 325 mesh * *>95% or more, increasing production by 10% and reducing energy consumption by 15%.
4. Reasonable system configuration, reducing investment in supporting equipment, and lowering system power consumption.
