Abstract

When performing a method for pneumatically conveying plastic pellets, the plastic pellets are conveyed, by means of a carrier gas, through a conveyor line from a feed point to a destination with a liquid being added thereto, wherein the quantity of liquid added to the plastic pellets and/or the carrier gas is such that during conveying, the carrier gas is oversaturated with the liquid at least in sections of the conveyor line in such a way that a Froude number defining the conveying conditions in the conveyor line is smaller than 45 at any point along the conveyor line.
