Abstract
The invention relates to the improving of a particle structure of carrier compounds for polymerization catalysts, and thereby to the improving of the activity of the entire catalyst, by jet grinding one or more carrier compounds (4), or a mixture of the same, in a grinding chamber in which one or more gas jets (2) transport particles (4) of the material to be ground finely, at such a force against each other and/or against one or more anvils (5) of the jet mill that the particles are pulverized into a finely-divided chemically active carrier.
