Abstract Polymer powder is separated from a carrier gas by separating the polymer powder from the carrier gas in a cyclone separator, drawing the thus-separated polymer powder through a bottom part of the separator into a hopper, feeding out the polymer powder by a rotary feeder from the hopper while controlling the revolution speed of the rotary feeder in accordance with the powder level in the hopper, controlling the volume of a purge gas, which is introduced into a polymer powder guide extending between the separator and the hopper for the prevention of plugging thereof, in accordance with the revolution speed of the rotary feeder, and the height of the top of the powder in the hopper is maintained at a predetermined constant level.
