Abstract
A tandem roller press has two roll pairs which are arranged next to one another in an axially parallel manner in order to provide a roller press system, in particular for the material bed comminution of granular material, which can considerably exceed previous limits with regard to throughput performance but also with regard to the specific energy requirement. Preferably, common feeding of the granular material and common discharge of the material which has been subjected to the material bed comminution are arranged. A tandem separator device may be arranged below the two roll pairs in order to form two parallel compact milling circuits with a high throughput performance overall.
