Abstract

The roller grinding mill for comminuting brittle grinding stock includes at least one grinding roller which co-operates with a counter-face in such a manner that the grinding stock is comminuted between the grinding roller and the counter-face and a pressing system for applying a force to the grinding stock via the grinding roller. The pressing system includes: at least one hydropneumatic store and at least one dual-articulation actuating cylinder. The dual-articulation actuating cylinder is connected to the hydropneumatic store and has two pistons and a housing which acts as a coupling rod.
