A growing number of researches believes that Dry Centrifugal Granulation (DCG) process is the most promising process in deal with the molten slag to raw material in cement produced on account of the no water consumes, no harmful gas emissions and efficient recovery of waste heat. Apparently, some obstacles, like every new technology, are on its way to industrialization. In this paper a new liquid slag feeding mode is present with a new way to control the flow rate of molten slag in order to gain fine particle diameter and high glassy phase.
