Slag powder has the advantages of improving various properties of concrete such as compression, tensile, shearing and bending resistance. It is more and more widely used and more and more popular in the market, especially the slag powder produced by chaeng. The specific surface area is 450m2 / kg, and the activity of slag can be fully exerted in 28 days. From the experimental data of Henan Mengdian, it is known that the addition of slag  powder can increase the strength of cement 28D by 15% -20%.

Due to the strong application of mineral powder, and the power consumption of the entire production line system does not exceed 43kWh / t, the low power consumption of grinding and the industry average level is very beneficial to reduce production costs, so the construction of slag powder production line has become the construction material industry to reduce cement costs Important measures.

Slag Grinding Plant

In terms of contracted output, chaeng conforms to the development of small and medium-sized enterprises and continuously expands the production range of the slag powder line. The main machine of the slag powder line with an annual output of 300,000 tons uses the GRMS33.41 slag vertical mill, which uses horizontal grinding discs and cone Shaped grinding roller to ensure that the material can form a stable material bed, low energy consumption, and save 30% to 40% compared with the ball mill system.
