Abstract
In a method and a device for producing a powder coating melt, firstly a first powder coating melt is produced from a powder coating premix by a screw machine. Powder coating particles are supplied to the first powder coating melt. Then a second powder coating melt is produced by mixing the first powder coating melt and the powder coating particles by the screw machine. This allows a simple, gentle and efficient recycling of powder coating particles, in particular of so-called off-spec powder coating particles.
