Crusher Control System Stress Deviation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling mineral material processing plants do not effectively consider the stress profile during the crushing process, leading to inefficient usage of capacity and potential equipment damage.
Innovation Solution
A method that measures stress-related quantities, determines deviation values, and adjusts default settings based on comparison to reference deviation values to optimize crusher operation, considering factors like pressure, load, and vibration, thereby improving capacity utilization and reducing wear on equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the crusher is operated with full capacity to maximize processing amount, then productivity is improved, but the stress on the crusher exceeds safety limits causing equipment damage
Solution Approach 1:
The control system continuously monitors the stress of the crusher during operation and compares it against predetermined safety limits. When the stress exceeds the limit, the system automatically adjusts operational parameters to reduce stress, creating a closed-loop feedback mechanism that maintains both high productivity and equipment safety
Solution Approach 2:
The system dynamically adjusts the operational parameters of the crusher based on real-time stress conditions. Instead of operating at a fixed capacity, the crusher operates at variable capacity that adapts to current stress levels, allowing maximum utilization when conditions permit while preventing damage when stress limits are approached
2Reliability
If a statistical peak value method is used to control stress, then stress limit compliance is improved, but the stress profile effect on the crushing process is neglected reducing efficiency
Solution Approach 1:
The system changes the control parameter from a simple statistical peak value to a comprehensive stress profile analysis that includes multiple parameters such as average stress, standard deviation, and temporal patterns. This allows the system to understand the complete stress characteristics and adjust operations accordingly, maintaining both safety compliance and crushing efficiency

AI summary
A method for controlling the operation of a crusher, a mineral material processing plant and a control system. The method including measuring a quantity related to stress to which the crusher is exposed during the crushing of material, determining a deviation value of the quantity related to stress, comparing the determined deviation value to a reference deviation value, and in response to the deviation value differing from the reference deviation value, adjusting a default setting of the quantity related to stress.
