Winged Hammer Tip Segmentation for Size Reducing Machine Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hammer tips in size reducing machines exhibit uneven wear patterns, leading to reduced throughput and increased power consumption, as well as excessive downtime due to the need for frequent repositioning and replacement of symmetrical tips with two working edges.
Innovation Solution
A hammer tip design comprising two sections: a production block with a single top working edge and a spacer block providing additional side working edges and a flat front surface, which can include wings for increased surface area, simplifying replacement and reducing downtime by allowing only single bolt removal and extending the lifespan of high-grade steel material.

Engineering Contradiction Analysis
1Duration of action of moving object
If symmetrical hammer tips with two top working edges are used, then the hammer tips can be reused by rotating them when one edge wears out, but this causes excessive downtime due to frequent repositioning and replacement
Solution Approach 1:
The hammer tip is divided into two distinct sections: a production block with a single top working edge and a spacer block with side working edges. This segmentation allows the production block to be replaced independently when worn, while the spacer block with its side edges continues to provide grinding capability, eliminating the need to rotate the entire hammer tip and reducing downtime.
Solution Approach 2:
The invention transitions from a symmetrical hammer tip design with two identical top edges to an asymmetrical design where the production block has a single top working edge and the spacer block has side working edges. This asymmetry prevents the need for rotation and allows for optimized placement of working edges to maximize throughput while minimizing replacement frequency.
2Productivity
If symmetrical hammer tips with two top working edges are used, then the hammer tips can be reused by rotating them, but this requires twice as many working edges compared to the number of hammers, leading to overly optimized positioning and excessive downtime
Solution Approach 1:
By segmenting the hammer tip into production and spacer blocks with different working edge configurations, the invention allows for more working edges per hammer without requiring rotation. The spacer block's side working edges are strategically positioned to provide additional grinding surfaces that increase overall productivity without the downtime associated with repositioning.
3Reliability
If high-grade steel material is used for hammer tips, then durability and wear resistance are improved, but the cost and material usage increase
Solution Approach 1:
The production block, which experiences the most wear, is made from high-grade steel material to ensure durability. The spacer block, which experiences less wear, can be made from lower-grade material or the same material but requires less frequent replacement. This segmentation optimizes material usage by applying high-grade material only where most needed.
Solution Approach 2:
The invention applies different material qualities to different sections of the hammer tip based on their wear requirements. The production block uses high-grade steel for maximum wear resistance in the high-stress top working edge area, while the spacer block's side working edges use adequate material that is sufficient for their lower-stress application, reducing overall material consumption.

AI summary
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 spacer block further includes a pair of wings extending outwardly from the left and right sides, and forwardly from the front side, of the spacer block to form additional cutting edges. The wings provide for additional sizing of the material being ground and help move (or push or carry) more material through the grates of the size reducing machine in the same amount of time as compared to spacer blocks without wings. This increased throughput improves efficiency of the size reducing machine.
