Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jaw crushers face limitations in efficiently adjusting the size of crushed inert material without causing excessive jaw wear or requiring multiple crushers, leading to high costs and reduced hourly output.
Innovation Solution
A jaw crusher equipped with a modular insert that allows for adjustable positioning of the jaws, enabling quick and efficient variation of crushed material size without excessive jaw inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cavity outlet opening is significantly reduced to obtain fine crushed material size, then the crushed material size is improved, but the jaw angle of inclination becomes excessively large which reduces the crushing surface area and increases jaw wear
Solution Approach 1:
The jaw is divided into a base portion and a removable insert portion. The insert can be exchanged with different lengths to achieve different outlet openings and crushed material sizes without changing the jaw's overall angle of inclination, thus maintaining crushing surface area while achieving fine material size
Solution Approach 2:
By changing the length of the insert component, the effective outlet opening of the cavity is adjusted. This allows variation in crushed material size while keeping the jaw angle constant, preventing excessive inclination and maintaining adequate crushing surface area
2Manufacturing precision
If the jaw angle of inclination is increased to reduce the cavity outlet opening, then the crushed material size is improved, but the crushing surface area is reduced and jaw wear increases
Solution Approach 1:
The jaw is segmented into a base portion and a removable insert. This segmentation allows the insert length to be varied to achieve different outlet openings without changing the jaw angle, thus preventing excessive inclination and maintaining crushing surface area to reduce jaw wear
Solution Approach 2:
The insert component provides dynamic adjustment capability. By replacing inserts of different lengths, the system adapts to different crushing size requirements while maintaining optimal jaw angle and surface area, reducing wear through consistent geometric conditions
3Manufacturing precision
If multiple crushers are used to obtain different crushed material sizes without excessive jaw inclination, then the crushed material size control is improved, but the device complexity and costs increase
Solution Approach 1:
A single jaw crusher is made multi-functional by enabling insert replacement. The same crusher can produce different crushed material sizes by changing the insert length, eliminating the need for multiple specialized crushers and reducing device complexity
Solution Approach 2:
The crusher system becomes dynamically adjustable through insert replacement. One crusher can adapt to different crushing requirements by changing its configuration, providing the functionality of multiple crushers in a single device
