To improve the operation of a roller press, a method is described according to which fluidized material that is discharged from the roller press over and above the sides of the roller press is collected and passed on to the next process stage together with the material which is ground in the roller press and discharged from the centermost section of the roller press. The remaining material which was ground in the roller press and discharged from the roller press through its end sections is returned to the roller press. By practicing the method of the present invention, a depletion of the material in the feed shaft is prevented due to a more stable roller feed, hence obtaining a smooth operation, even for high circulation factors, a higher average power absorption and a higher output level.
