The present invention relates to a method for adjusting the average particle size of a spherical catalyst support comprising a magnesium dihalide-ethanol adduct, a spherical catalyst support obtained by the method, a polymerization catalyst comprising the spherical catalyst support, and a process for the polymerization of olefins by use of the polymerization catalyst. La présente invention concerne un procédé de réglage de la taille moyenne des particules d'un support de catalyseur sphérique comprenant un produit d'addition éthanol-dihalogénure de magnésium, un support de catalyseur sphérique obtenu selon le procédé, un catalyseur de polymérisation comprenant le support de catalyseur sphérique, et un procédé de polymérisation d'oléfines à l'aide du catalyseur de polymérisation.
