Abstract
In a powder coating system wherein the powder is introduced via a feed conduit from the feed point to a mixing chamber, a pressure gradient oriented against the chamber is produced along the feed conduit by acceleration of a gas jet in the mixing chamber, and pressure recovery is obtained by retarding the powder-gas stream, in order to feed the powder-gas stream through a conveying line to a coating unit. For increasing the quantity of powder dispensed per unit time to the powder coating system, the pressure drop in the powder-gas stream along the conveying line is at least in part compensated for by raising the pressure at the feed point.
