Abstract

A process and apparatus is disclosed comprising a high-speed rotation bell for applying quick-evaporating fluids, such as quick-evaporating liquid paint, wherein the impact deposition of largely evaporated paint particles on the high-speed rotation bell is prevented by affecting the flight path of the paint particles flying back in the zone of the toroidal vortex toward the high-speed rotation bell with electric or magnetic or aerodynamic forces or combinations of these forces.
