Liner Plate Edge Protection Using Segmented Carbide Tiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Equipment in material processing handling systems, such as crushers, experiences significant wear due to the transportation of heavy materials like rocks and stones, leading to frequent replacements and increased maintenance costs.
Innovation Solution
A liner plate with edge protection, featuring primary wear tiles made of cemented carbides metallurgically bonded to a matrix material, provides enhanced wear resistance and durability. The tiles have a flat or rounded outer surface and backward protrusions that anchor them securely to the plate, reducing the need for frequent replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plates are used in material processing handling systems to transport heavy materials, then material transportation is enabled, but the plates experience significant wear and require frequent replacements
Solution Approach 1:
The plate is divided into a base plate and separate wear tiles that can be independently replaced. The wear tiles are segmented into multiple primary wear tiles arranged along the edges and secondary wear tiles in the center area, allowing only the worn tiles to be replaced rather than the entire plate.
Solution Approach 2:
Different regions of the plate are given different levels of wear protection based on their specific wear exposure. Edge regions with higher wear risk receive primary wear tiles with backward protrusions for secure anchoring, while the center area receives secondary wear tiles, optimizing protection where most needed.
Solution Approach 3:
The plate combines a base plate material with wear tile materials that have superior wear resistance properties. The wear tiles are made from materials specifically selected to resist the wear caused by heavy material transportation, creating a composite structure that optimizes both durability and wear resistance.
2Reliability
If edge protection is added to the plate, then wear resistance is improved, but device complexity increases
Solution Approach 1:
The edge protection is segmented into multiple primary wear tiles rather than being a single complex component. Each tile is a simple unit with a backward protrusion, and multiple tiles work together to provide comprehensive edge protection, simplifying manufacturing and replacement.
Solution Approach 2:
The backward protrusions on the wear tiles are pre-formed during manufacturing, creating ready-to-anchor features that simplify the installation process. The tiles are designed to be pre-assembled or pre-positioned in specific patterns along the plate edges.
