Abstract
A process and device are disclosed for producing microspheres by vibration-provoked dripping of a liquid through a nozzle plate (12) provided with several openings (14). In order to be able to produce spheres having up to 5 mm size, the same amount of liquid per unit of time drips through each opening (14) of the nozzle plate (12). The falling drops (18) form an envelope surrounded from all sides by flowing reaction gas. The reaction gas is introduced inside or outside the envelope and sucked away inside or outside the envelope.
