ABSTRACT:
A method for making granules from sprayed molten material falling through a tower in which a substantial amount of the rising cooling gas stream is withdrawn from the tower at a level below the top of the tower and is discharged to atmosphere. Only the remaining gas stream requires treatment to remove dust and other pollutants, resulting in a considerably lower energy consumption at the same environmental pollution compared with other processes and installations known.
