Recirculating grinding mill with external risers

A recirculating grinding mill, comprising:

• at least two rolling presses for comminuting 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 rolling presses, first classifiers and the at least one second classifier being arranged such that feedstock fed into the recirculating grinding mill passes 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 are fed again to the rolling presses, and
• the at least two first classifiers being arranged underneath the at least two rolling presses,
• wherein transport of the fractions classified in the at least two first classifiers is provided through at least two risers, the at least two rolling presses being arranged between the at least two risers, and the second classifier is a rod cage classifier with a rod cage spaced within a classifier housing, the rod cage classifier having in a region between the classifier housing and the rod cage at least two separating walls, by which a space in the rod cage classifier outside the rod cage, but within the classifier housing, into which material to be classified is fed, is divided into more than one space, and these divided spaces each have at least one individual classifying-material feed and each have at least one individual coarse-material discharge.
