Oct 01, 2007 The blast furnace water-cooled slag (BFWS) used throughout in this research was obtained from Sumitomo Metals Ltd. in Japan. The BFWS was ground with a ball mill to obtain a BET specific surface area of 370 m 2 kg. According to our previous investigations [8–9], additions of Portland cement and slaked lime into municipal incineration ash and coal flyash were favorable to the.
Feb 18, 2019 The vertical roller mill is a grinding equipment that has both the functions of crushing and grinding, and uses the material to be ground to work as a medium. The slag vertical mill is similar to the ball mill, but the vertical grinding principle and structure are quite different from those of the ball mill. In the following, the vertical mill manufacturer chaeng will analyze the difference.
