Abstract

A high pressure roll press has two counter-rotating rolls configuring a roll nip through which milling material passes and is comminuted under high pressure by forming a fracture in a milling material structure in the roll nip. A feeder device feeds the milling material homogeneously onto the roll nip. The volume of the fed milling material configures a compaction zone, which reaches from approximately the center of the roll nip to just beyond the center of the roll nip. A vibration device for pre-compressing the milling material is arranged above the compaction zone, reaching into the compaction zone. A metering slide is arranged within the feeder device to set the feeding location and the feeding quantity of the milling material onto the roll nip. The vibration device is connected to the metering slide, wherein the metering slide conducts the vibration energy of the vibration device into the compaction zone.
