High performance VU aggregate optimization system

Sand and gravel is the main raw material indispensable transportation construction, infrastructure construction, with the pace of the country, speed up infrastructure construction, the amount of sand and gravel aggregate demand China rapid growth, currently more than 100 tons, the scale of the industry in more than 500000000000 yuan. However, the growing shortage of resources caused by the river sand in short supply, prices rise, and the quality fluctuation, while the traditional mechanism of multi angle, graded sand rough uneven, too many impurities, lack of performance, the aggregate shortage in the construction industry is undoubtedly one disaster after another. In the face of the huge market demand, aiming at the shortage of traditional process, liming heavy industry with the domestic and foreign advanced technology and research results, with high efficiency, economy and technology rich powder grinding sand process, through the whole process of demonstration and experiment, on the basis of original dry sand system for update and comprehensive upgrade, the launch of the VU series of aggregate optimization system in dry sand, a new solution to solve production problems of high-quality manufactured sand. The tower height intensive closed arrangement, efficient system sand, grain, powder, gradation adjustment optimization control, moisture control, environmental protection in one, not only improves the production efficiency, to achieve a more comprehensive promotion mechanism of sand type, gradation, powder quantity indicators, in line with standard sand concrete, can be used for mixing station, dry mixed mortar, cement factory and other supporting system of sand, sand aggregate mine facilities, large construction projects supporting the sand and so on, which can meet the huge market demand for high quality sand, with good investment value, has been repeatedly verified in the two beach, Xiaolangdi Dam, Wuqiangxi project.

The VU system in the dry process the most reasonable, the greatest degree of reproducing the natural sand in the process of formation of natural fracture, erosion of friction, natural washing effect, the properties of the finished products significantly enhance the sand. VU system can use cheap tailings, waste, construction waste, "stone", "Guami stone as raw material, using the dry process of environmental protection, output distribution is reasonable, grain type rounded, with controllable finished powder sand, dry and clean, and can be unified powder high value-added recycling. According to the material determines the scope of application of slag fine powder can be used as the output of the limestone asphalt concrete mixing station, to cement material, used in waterproof paint factory as raw material, can be used for power plant desulfurization, unburned brick produced; output of fine powder can be used as Xuan Wuyan do special acid, alkali cement, Xuan Wuyan fiber raw materials, the production of unburned brick and stone. The VU properties of VU series sand aggregate optimization system produced comparable to natural sand, creating new opportunities for the development of sand, cement, concrete industry chain and value, will promote the transformation of sand industry.
