In order, in the pelletising of fine-grained material, in particular in the grinding of the material to pelletising fineness, to save investment and operating costs, above all energy and wear costs, and to reduce the introduction in particular of iron impurities into the ground material and thus into the pellets, it is proposed according to the invention that, before it is pelletised in a pelletising device (10), the material (13) is subjected to a material-bed comminution in the roller gap of a high-pressure roller press (11) and, in the process, comminuted or ground to pelletising fineness, that is to say to a grain size smaller than approximately 100 mu m. <IMAGE>
