Patent attributes
The invention makes public an environment-friendly non-noise matte granulation technique. Melted matte flows out from the chute, 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 dispersed tiny drops to semi-melted or solid copper grains; in the following dropping course, the copper grains are quenched by pressurized cold water; finally, copper grains drop to the cold-water pond along with the pressurized cold water for further cooling, and the produced sand-like mattes are sent to the next procedure through dehydration-and-transportation system. It can overcome explosion and prevent chemical reaction in quenching, reduce noise pollution, and has the properties of simple procedure and easy operation to settle the problems existed in water quenching of matte.
