Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wear-resistant coverings for machinery, such as grinders, require extensive assembly and repair times, and frequent replacement of entire coverings due to uneven wear patterns, leading to inefficiencies in production cycles, especially in continuous grinders.
Innovation Solution
A wear-resistant panel system featuring a matrix with cavities of specific dimensions and shapes to securely anchor hard, alumina-based inserts, allowing for precise distribution and varying projection levels to optimize wear resistance, which can be assembled using adhesive or forced coupling without the need for complex vulcanization processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alumina-based bricks are arranged and cemented to cover inside walls of grinding chambers, then wear resistance is improved, but assembly time and repair complexity increase significantly
Solution Approach 1:
The covering is divided into modular panels that can be independently assembled and replaced. Each panel contains multiple cavities that hold individual alumina-based inserts, allowing selective replacement of only the worn panels rather than the entire covering system.
Solution Approach 2:
The alumina-based inserts are pre-assembled into panel structures with cavities before being installed on the grinding chamber. This preliminary assembly reduces on-site installation time and complexity, as the panels are prepared in advance and can be quickly mounted using adhesive or forced coupling.
2Loss of time
If wear-resistant rubber coverings are used, then assembly time is reduced, but frequent replacement of entire coverings is required due to uneven wear patterns
Solution Approach 1:
The covering system is segmented into multiple panels with individual alumina-based inserts. This allows only the worn inserts or panels to be replaced rather than the entire covering, extending the service life of the non-worn portions and reducing material waste.
Solution Approach 2:
Hard alumina-based inserts are strategically placed in specific cavities on the panel surfaces that correspond to high-wear zones. This local reinforcement provides enhanced wear resistance where needed while maintaining the flexibility and ease of assembly of the rubber-based panel structure.
3Reliability
If alumina-based bricks are inserted into rubber base by pressing and vulcanization, then wear resistance is improved, but manufacturing complexity and process time increase
Solution Approach 1:
The complex vulcanization process is extracted and replaced with simpler assembly methods. The alumina-based inserts are placed into pre-formed cavities in the rubber panels and secured using adhesive or forced coupling, eliminating the need for pressing and vulcanization operations while maintaining structural integrity.
Solution Approach 2:
The chemical bonding process of vulcanization is replaced with mechanical assembly methods such as forced coupling or adhesive bonding. This substitution simplifies the manufacturing process, reduces process time, and allows for easier disassembly and replacement of inserts without requiring complex thermal or chemical processing equipment.

AI summary
The invention relates to a process for realizing wear-resistant panels usable for the formation of anti-wear surfaces, comprising the following steps: - forming a matrix (2) having a support function and which is provided, on a work surface (3), with a plurality of cavities (4), which are dimensioned and shaped to accommodate wear-resistant inserts (5) of matching size and are distributed over said work surface (3) according to a pre-established order and geometrical arrangement; - spreading adhesive, if necessary; - inserting the inserts (5) in the cavities (4); - curing, if necessary. The reciprocal coupling surfaces of the cavities (4) and the respective inserts (5) are shaped to allow accurate centring of the inserts (5) in the cavities (4) and a pre-established distribution of any adhesive in the coupling zone.
