US [VERTICAL SHAFT IMPACTOR]

As shown below, for the same raw material, US can greatly increase the absolute volume compared with the use of Horizontal Shaft Inpactor.

  Size Raw Material Solid content

US
Aggrgate 20-5 Andesite 55% 58% 60%
Sand 2.5-1.2 Sandstone 50% 53% 56%

The improvement of the absolute volume rate of the aggregate can reduce both consumptions of unit volume of water and amount of cement for concrete. For example,when the water-cement ratio w/c is 1/2, the improvement 1% of absolute volume rate of the aggregate can reduce unit volume of water by 2kg, and amount of cement by 4kg. The absolute volume rate of material of aggregate in the table above is 55%, on the other hand through US the absolute volume rate will attain 60%, that is, the improvement of rate is consequently increased by 5%. In this case, water can be reduced by 10kg and cement by 20kg.

US Sales Performance

After the mid-1980s, compared with the use of the other Horizontal Shaft Impactor, the use of US can have the cost advantage and significantly improve the aggregate grain shape. And these two points are well certified by the markets. The sales of US in Japan rapidly have increased, 1500 machines have sold so far. Since the late-1980s, US have been exported to Europe and the United States and other countries and regions, and have received praise and popular from the customers.
