Described is a comminution device, in particular a comminution device including an adjusting mechanism, the adjusting mechanism including a hydraulic cylinder which is coupled between the first and the second cutting element and is in hydraulic communication with a closed hydraulic and pneumatic volume, which is filled with a hydraulic fluid in a first part and with air in a second part, and the wall of which is at least partially transparent so that the hydraulic fluid level can be read from a scale which displays a wear condition of the first and second cutting element.Also detailed is a comminution device in which a lubricant-filled cavity is formed between a first area and a second area, the volume of the cavity being reduced by an adjusting movement of the second cutting element and which is in fluidic communication with the positive engagement connection in order to supply lubricant to the positive engagement connection.
