Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gyratory cone crushers face issues with premature liner wear, component damage, and inconsistent production due to movement or separation of liners from the crushing components, leading to significant downtime and maintenance challenges.
Innovation Solution
The implementation of movement detectors that monitor relative movement between the liners and crushing components, using sensors and circuits to detect changes in physical properties and send signals for alarm or operational adjustments, ensuring timely maintenance and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If movement detectors and sensors are implemented to monitor liner movement, then detection precision and reliability are improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical detection systems with electromagnetic sensors and electronic circuits. The movement detector uses electrical resistance changes, capacitance variations, or inductance changes to detect liner movement, substituting mechanical linkages and physical contact systems with field-based detection methods that achieve high precision without mechanical complexity.
Solution Approach 2:
The patent introduces electromagnetic fields as intermediaries between the liner and the detection system. Sensors detect changes in electrical resistance, capacitance, or inductance that occur when the liner moves, using these electromagnetic properties as mediators to translate physical movement into detectable electrical signals without requiring direct mechanical coupling.
2Reliability
If early detection systems are implemented to prevent liner movement damage, then reliability is improved, but loss of time for installation and maintenance increases
Solution Approach 1:
The patent implements movement detectors that continuously monitor liner position and send alerts before significant movement or damage occurs. By detecting early signs of liner displacement through changes in electrical resistance, capacitance, or inductance, the system enables planned maintenance scheduling rather than reactive repairs, improving reliability while minimizing unplanned downtime.
Solution Approach 2:
The patent incorporates feedback mechanisms where sensors continuously monitor liner movement and provide real-time information to operators. The system compares detected parameters against threshold values and triggers alerts when abnormal movement is detected, enabling timely intervention before damage occurs and optimizing maintenance timing to minimize production loss.
