Production plus hammer tip
A hammer tip for releasable integration with a hammer, used in a size reducing machine. The hammer tip is separated into a production block with a top working edge and a spacer block. The production block and spacer block utilize a saddle back attachment to the hammer. The production block is further supported with a lock ledge integration to the spacer block. The production block with a single top working edge reduces maintenance cost, reduces downtime and improves machine throughput.
1. A hammer tip, the hammer tip comprising:
a production block comprising a body having a front side, a back side, a top working edge and an opening formed in the body and extending between the front side of the production block and the back side of the production block, the opening configured to receive a first bolt to attach the production block to a hammer; and
a spacer block comprising a body having a front side, a back side and an opening formed in the body and extending between the front side of the spacer block and the back side of the spacer block, the opening configured to receive a second bolt to attach the spacer block to the hammer,
wherein the production block and the spacer block each comprise a saddle back formed on their respective back sides and configured to engage with a hammer for releasable attachment thereto,
wherein the production block comprises a lock pocket, the lock pocket formed as a recess along a width of the front side of the production block, and the spacer block comprises a lock ledge, the lock ledge formed as a ledge along a width of the back side of the spacer block,
wherein the lock pocket of the production block is configured to matingly engage with the lock ledge of the spacer block when the production block and spacer block are attached to the hammer to hold the production block against the hammer and to prevent the production block from tilting away from the hammer when the top working edge of the production block is impacted by a grinding material.
2. The hammer tip of claim 1 wherein the top working edge of the production block includes a wear resistant coating.
3. The hammer tip of claim 1 wherein the top working edge of the production block is hardened.
4. The hammer tip of claim 1 wherein at least a portion of the front side of the production block includes a wear resistant coating.
5. The hammer tip of claim 1 wherein substantially all of the front side of the production block includes a wear resistant coating.
6. The hammer tip of claim 1 wherein the production block further comprises a pair of side working edges, the side working edges each including a wear resistant coating.
7. The hammer tip of claim 1 wherein the production block further comprises a pair of side working edges, the side working edges each being hardened.
8. The hammer tip of claim 1 wherein at least a portion of the front side of the spacer block includes a wear resistant coating.
9. The hammer tip of claim 1 wherein substantially all of the front side of the spacer block includes a wear resistant coating.
10. The hammer tip of claim 1 wherein the production block further comprises a pair of side working edges, and the top working edge and the side working edges of the production block include a wear resistant coating.
11. The hammer tip of claim 1 wherein at least a portion of the front side of the production block and at least a portion of the front side of the spacer block each include a wear resistant coating.
12. The hammer tip of claim 1 wherein substantially all of the front side of the production block and substantially all of the front side of the spacer block each include a wear resistant coating.
