Abstract

The invention relates to a method for transporting foamed thermoplastic polymer particles (3) from a container (5, 9) through at least one pipe (7,9), wherein, for transporting the foamed thermoplastic polymer particles (3), a gas stream is applied through the pipe (7, 11). The foamed thermoplastic polymer particles (3) are wetted with a water comprising lubricant.
