Wear-resistant element for a comminuting device
View Patent ↗A wear-resistant element for partial insertion into a recess on the surface of a wear area of a comminuting device. The wear-resistant element includes particles made of a highly wear-resistant material which are embedded in a matrix material.
1. A comminuting device, comprising:
a roller main body comprising a wear area including a recess formed in a surface of the wear area;
a wear-resistant element configured to be partially inserted into the recess, the wear-resistant element comprising:
a core region; and
a shell region surrounding some or all of the core region;
wherein both the core region and the shell region are composed of a matrix material comprising tungsten carbide; and particles of diamond, ceramic, or titanium, embedded exclusively in the core region.
2. The comminuting device of claim 1 , wherein the particles of diamond, ceramic, or titanium are distributed uniformly in the matrix material or are concentrated at a selected position within the matrix material.
3. The comminuting device of claim 1 , wherein the shell region and the core region are bonded to one another.
4. The comminuting device of claim 1 , wherein the shell region and the core region are sintered to one another.
5. The comminuting device of claim 1 , wherein the particles of diamond, ceramic, or titanium are arranged in the core region in such a manner that a particle distribution density rises with proximity to the shell region.
6. The comminuting device of claim 1 , comprising:
a fastening region, which is configured to connect to the recess on the surface of the wear area of the comminuting device; and
a wear region, which protrudes at least partially out of the surface of the wear area of the comminuting device.
7. The comminuting device of claim 6 , wherein exclusively the wear region comprises the particles of diamond, ceramic, or titanium which are embedded in the matrix material.
8. The comminuting device of claim 6 , wherein an end face of the wear-resistant element comprises a cutout.
9. The comminuting device of claim 6 , wherein a material of the fastening region has a lower wear resistance than a material of the wear region.
10. The comminuting device of claim 6 , wherein the fastening region has a sleeve-shaped form, wherein the wear region is arranged within the sleeve-shaped form of the fastening region.
11. The comminuting device of claim 7 , wherein the fastening region and the wear region are bonded to one another.
12. The comminuting device of claim 7 , wherein the fastening region and the wear region are adhesively bonded or soldered to one another.
13. The comminuting device of claim 7 , wherein the fastening region comprises less than 45% of the wear-resistant element.
14. The comminuting device of claim 1 , wherein a fastening region of the wear-resistant element is bonded to the recess.
