Claim:
Environment-friendly non-noise matte granulation method comprising following processes: melted matte flows out from a chute, and then gas is sprayed on the matte through spray facilities; the gas disperses the melted matte into a large amount of tiny liquid drops, and cools the tiny liquid drops to semi-melted or solid copper grains; in following dropping course, the matte grains are quenched by pressurized cold water; finally, the matte grains drop to a cold-water pond along with the pressurized cold water for further cooling and become sand-like mattes, which are sent to next process through a dehydration-and-transportation system; stirring sprayers are installed in the cooling pond, pressurized cold water is sprayed from the stirring sprayers to conduct stirring heat-exchange, and produced steam is discharged to ambient air through a discharge chimney.
