The invention relates to a method for changing the structure of minerals or the like, especially for micronizing said minerals or the like, especially in an apparatus which comprises rotors with baffles between which the minerals or the like are subjected to a dynamic impact and/or friction process in a housing. Counter-rotary rotors are designed as rotor discs the baffles of which are arranged in a ring and extend axially into the interior of the housing such that the rotor discs, when in operation, pass by one another without touching. According to the invention, the grains of the minerals can be electrostatically charged by way of said treatment. |
