Comminution device

摘要

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.

主权项

1. A comminution device, comprising:
a first cutting element, including at least one first cutting edge, a second cutting element which is movable on a first path of movement relative to the first cutting element and which has at least one second cutting edge,wherein the second cutting element lies against the first cutting element in such a way that the relative movement of the second cutting element along the first path of movement produces a shearing action between the at least one first cutting edge and the at least one second cutting edge,
an adjusting mechanism which adjusts the second cutting element relative to the first cutting element on a second path of movement in such a way that the second cutting element is moved closer for permanent contact with the first cutting element when at least one of the first or second cutting elements wears down as a result of the relative movement along the first path of movement,wherein the adjusting mechanism has a leak-free hydraulic cylinder which is coupled mechanically and functionally between the first and the second cutting elements
in order to bring about an adjusting movement between the first and the second cutting elements by actuating the hydraulic cylinder and to cause the first and second cutting elements to contact each other by application of pressure to the hydraulic cylinder, and in that the hydraulic cylinder is in hydraulic communication with a closed hydraulic and pneumatic volume which includes a pressure vessel, the volume of 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 defines the boundary region ensuing during operation between an air volume fraction and a hydraulic fluid volume fraction in the closed hydraulic and pneumatic volume and displays a wear condition of the first and second cutting element.
