ABSTRACT:
An atomizer has a channel through which material to be atomized, preferably comprising a transport gas and a powder, liquid or granular material, flows in a first direction. At or slightly downstream from the downstream end of the channel, preferably an atomizer gas is injected into the stream to be atomized, the injection occurring at an angle to the first direction. Preferably the atomizer gas is injected to impart a rotary motion to the stream. At the downstream end of the channel is a funnel-shaped outlet whose surface is so shaped that the stream can adhere to the interior surface of the outlet under the Coanda effect, producing an atomized cloud of transversely uniform density. A gas jacket may be used to control the shape of the cloud. The flow of both the atomizer gas and the gas forming the gas jacket is preferably adjustable in speed and direction.
