Wear-resistant element for a comminuting device
View Patent ↗A wear-resistant element for partially inserting into a recess in the surface of a wear surface of a comminuting device. The wear-resistant element has a fastening region, which is connectable to the recess in the surface of the wear surface and a wearing region, which protrudes at least partially from the surface of the wear surface. The fastening region includes a material that is less wear-resistant than the material of the wearing region, wherein the wearing region extends beyond the fastening region at the level of the wear-resistant element.
1. A comminuting device, comprising:
a grinding roller including a wear surface with a recess;
a wear-resistant element configured to partially insert into the recess, the wear-resistant element comprising:
a fastening region, and
a wearing region,
wherein the fastening region comprises a material that is less wear-resistant than the material of the wearing region, wherein the wearing region extends outwardly from the fastening region and wherein the fastening region includes a sleeve region that circumferentially surrounds the wearing region,
wherein the fastening region has a receiving region for receiving the wearing region, which is configured such that it centers the wearing region relative to the fastening region, and
the receiving region has a cutout and the wearing region has a protrusion which is configured to cooperate with the cutout to fit to the cutout and position the wearing region on the fastening region,
or wherein the receiving region has a protrusion and the wearing region has a cutout which is configured to cooperate with the protrusion to fit to the protrusion and position the wearing region on the fastening region.
2. The comminuting device of claim 1 , wherein the material of the wearing region comprises a ceramic material.
3. The comminuting device of claim 1 , wherein the material of the fastening region comprises a steel.
4. The comminuting device of claim 1 , wherein the wear-resistant element has an end-side cutout which faces in the direction of the wear surface.
5. The comminuting device of claim 1 , wherein the wear-resistant element has a bore which faces in the direction of the wear surface.
6. The comminuting device of claim 1 , wherein the wearing region is arranged at least partially within the sleeve of the fastening region.
7. The comminuting device of claim 1 , wherein the fastening region and the wearing region are bonded together.
8. The comminuting device of claim 1 , wherein the fastening region and the wearing region are adhesively bonded or soldered together.
9. The comminuting device of claim 1 , wherein the fastening region comprises less than 45% of the wear-resistant element.
10. The comminuting device of claim 1 , wherein the fastening region comprises less than 30% of the wear-resistant element.
11. The comminuting device of claim 1 , wherein the fastening region comprises less than 20% of the wear-resistant element.
12. The comminuting device of claim 1 , wherein the wear-resistant element is recessed at least partially in the wear surface.
13. The comminuting device of claim 1 , wherein the fastening region of the wear-resistant element is bonded to the grinding roller.
14. The comminuting device of claim 1 , wherein the fastening region of the wear-resistant element is welded, adhesively bonded or soldered to the grinding roller.
