Abstract
A crushing ring of a crushing roll includes a base body with a through-opening, for connecting it to a shaft in a rotationally rigid fashion. At least one crushing tooth is in the form of a projection that is provided on the outer circumference of the base body and extends radially outward. A crushing cap encases the projection. The crushing cap includes a front wall section, a rear wall section and a head section that connects the two. A first pin-shaped connecting member detachably mounts the crushing cap on the projection. A second pin-shaped connecting member also detachably mounts the crushing cap on the projection. The second connecting member extends through the rear wall section of the crushing cap and is separably held in the projection.

A crushing ring of a crushing roll, comprising a base body with a through-opening, by means of which the base body can be connected to a shaft in a rotationally rigid fashion, at least one crushing tooth in the form of a projection that is provided on an outer circumference of the base body and extends radially outward, and a crushing cap that encases the projection at least in a circumferential direction, with said crushing cap including a front wall section in relation to a rotational direction of the crushing ring, a rear wall section and a head section that connects the front wall section to the rear wall section,
- wherein a first pin-shaped connecting member is provided for separably mounting the crushing cap on the projection, with said first connecting member extending through the front wall section of the crushing cap and being separably held in the projection,
- wherein a second pin-shaped connecting member is provided for separably mounting the crushing cap on the projection, wherein the second connecting member extends through the rear wall section of the crushing cap and is separably held in the projection, and wherein a longitudinal axis of the second pin-shaped connecting member extends at an angle (α) of 90° relative to a rear wall surface of the projection in relation to the rotational direction of the crushing ring or at an angle of less than 90° relative to the section of the rear wall surface of the projection that lies between the second connecting member and the head section of the crushing cap.
A crushing ring of a crushing roll, comprising a base body with a through-opening, which is configured to allow the base body to be connected to a shaft in a rotationally rigid fashion, a crushing tooth including a first projection that is provided on the outer circumference of the base body and extends radially outward, and a crushing cap that is adapted to encase the first projection at least in a circumferential direction, said crushing cap including a front wall section in relation to a rotational direction of the crushing ring, a rear wall section and a head section that connects the front wall section to the rear wall section,
- a first pin-shaped connecting member for detachably mounting the crushing cap on the first projection, said first connecting member extending through the front wall section and being detachably held in the first projection,
- a second pin-shaped connecting member for detachably mounting the crushing cap on the first projection, wherein the second connecting member extends through the rear wall section of the crushing cap and is detachably held in the first projection, and
- wherein a longitudinal axis of the second pin-shaped connecting member extends at an angle (α) of 90° relative to a rear wall surface of the first projection in relation to the rotational direction of the crushing ring or at an angle of less than 90° relative to the section of the rear wall surface that lies between the second connecting member and the head section of the crushing cap.
