Abstract
A process for producing dispersion powders by spray drying of aqueous polymer dispersions and addition of antiblocking agents in a rotary atomization dryer, wherein the antiblocking agent is conveyed by delivery air, wholly or partly, into an annular gap which is formed by a moulding arranged concentrically around the housing of the rotary atomizer, and which ends at a distance above the upper edge of the atomizer plate of the rotary atomizer.
