Gyratory Crusher Shell Segmentation for Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gyratory crusher outer shells face significant wear and distortion due to high pressures and impact loading, necessitating structural reinforcement, but existing backing compounds are hazardous, environmentally unfriendly, and require long curing times, leading to extended downtime and unpredictability in high-pressure applications.
Innovation Solution
The design features a gyratory crusher outer shell with axially raised contact sections separated by channels that can be filled with backing material, allowing for in-situ modification and reinforcement, compatible with various backing materials, including environmentally friendlier options, to maintain shell integrity and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If backing compounds are used to structurally reinforce the outer shell, then the shell strength and structural support are improved, but the health and environmental hazards increase
Solution Approach 1:
The contact region is segmented into discrete sections separated by grooves, allowing selective reinforcement only where structural support is needed rather than requiring hazardous backing compounds throughout the entire shell structure
Solution Approach 2:
The shell transitions from uniform structure to having localized raised contact sections with varying thicknesses, providing targeted structural reinforcement at specific locations while avoiding the need for hazardous backing materials in non-critical areas
2Strength
If traditional backing compounds are used for reinforcement, then structural support is improved, but the curing time and crusher downtime increase
Solution Approach 1:
The shell is pre-formed with integrated raised contact sections and grooves during manufacturing, eliminating the need for time-consuming application and curing of backing compounds in the field. The structural reinforcement is built-in rather than added later
Solution Approach 2:
The invention extracts and removes the need for separate backing compound materials and their associated curing processes by integrating the reinforcement structure directly into the shell design
3Adaptability or versatility
If the shell design is modified to allow in-situ reinforcement, then the adaptability and ease of modification are improved, but the device complexity increases
Solution Approach 1:
The contact region is divided into discrete sections separated by grooves, creating a modular structure that is easier to manufacture and assemble while providing the adaptability needed for selective reinforcement
Solution Approach 2:
The grooves serve multiple functions: they separate contact sections, provide pathways for backing material if needed, and facilitate the modular construction of the shell, reducing overall complexity despite the enhanced adaptability

AI summary
A gyratory crusher outer crushing shell (106). The outer crushing shell comprises an upper contact surface region (128) that is divided into a plurality of elongate circumferentially extending shoulders (204). The shoulders are separated by recessed gap regions (200) adapted to accommodate a suitable backing material to structurally reinforce the shell. A channel (201) extends circumferentially around the shell in the outward facing surface to axially separate the upper contact surface region from a lower contact surface region (129). The channel is also adapted to accommodate the backing material.
