| 摘要 |
The invention relates to a comminution device, particularly comprising an adjusting mechanism which has a hydraulic cylinder (165, 167) that is coupled between the first and the second cutting element and is in hydraulic connection to a hydraulic, pneumatically closed volume (220, 230). A first part (220a) of said volume is filled with a hydraulic fluid, a second part (220b) thereof is filled with air and the walls thereof are at least partially transparent in order to be able to read out the hydraulic fluid level along a scale (222) which displays a wear state of the first and second cutting element. The invention further relates to a comminution device in which a lubricant-filled cavity (380) is formed between a first surface (32; 453) and a second surface (342; 463), the volume of said cavity being reduced by an adjustment movement of the second cutting element and said cavity being in fluidic connection with the form-fitting connection for supplying lubricant to said form-fitting connection. |
