Abstract
At present, centrifugal granulation has become the most promising method for waste heat recovery of molten slag. This paper investigates the effects of rotary disk configurations on particles characteristics with molten aluminum as the working medium. Four types of rotary disks and two kinds of particles characteristics which included particles size distribution and particles mean size were studied. It can be seen that the main particles sizes are populated in the range of 2.0~4.0mm for all disk configurations. Due to the special surface structure, the particles produced by curved-block disk and arc-edge disk configurations are more concentrated compared to other two types of disks. Besides, the results shown that the mean size of particles generated by curved-block disk is smaller. All the conclusions will be helpful for future development of the high-temperature molten slag dry granulation systems.
