In this method of comminution according to the invention, pre- comminuted ore material is subjected to material bed comminution in a material bed roll mill. In order to achieve optimal comminution even of very different ore materials with a high throughput the ore material is pre-comminuted in an autogenous mill, whereupon at least fractions of fine material are separated out of the pre-comminuted material before the rest of the material is further comminuted in the material bed comminution.
