MATHEMATICAL MODELING AND MOTION CONTROL OF A SINGLE DROPLET OF BLAST FURNACE SLAG IN THE GAS FLOW DURING DRY GRANULATION
Dry granulation plants of blast furnace slag allow obtaining granulated slag and use heat of liquid slag. When introducing dry granulation of slag, emissions of harmful sulfur compounds into the atmosphere are excluded. When designing the granulation chamber, it is necessary to evaluate the main size of the chamber - its diameter to avoid slag sticking to the walls of the chamber. The slag droplets must solidify before colliding with the wall. In this work, the authors developed a mathematical model for the movement of a single droplet of molten blast furnace slag during dry granulation, which allows controlling the cooling process of a single droplet of molten blast furnace slag in the granulation chamber.
