A method for regulating the roll gap pressure of a roller press and a corresponding roller press. The roll gap pressure is regulated dependent on at least one oscillating movement that is measured on the roller press. This has the advantage that the roller press can always be operated at the maximum roller press efficiency without the roller press reaching the overload range.

Method for regulating the roll gap pressure of a roller press

A recirculating grinding mill, including at least two rolling presses for comminuting the material to be ground, at least two first classifiers for classifying a coarse-grain fraction, at least one second classifier for classifying a fine-grain fraction and a medium-grain fraction from the fractions classified in the at least two first classifiers. The feedstock is fed into the recirculating grinding mill passing the at least two rolling presses and the at least two first classifiers and then the at least one second classifier and the medium-grain fraction and the coarse fraction of the at least two first classifiers being fed once again to the rolling presses, and the at least two first classifiers being arranged underneath the at least two rolling presses. The rolling presses are placed between at least two risers for transporting the circulating material being ground.
