The feed pipe should naturally be of stainless steel and of course of the
high-pressure type, if the atomization is to be carried out by means of
nozzles. The dimension should be so that the feed velocity is approx. 1.5
m/sec. In a feed system a return pipe and a device to clean the rotary
atomizer, incl. the weel, as well as the nozzle lances, should also be included
for the cleaning solution, so that the entire equipment can be thoroughly
cleaned.
