Material Buffer Feed Planning for Uniform Rock Processing Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rock processing apparatuses face inefficiencies in material flow management, particularly in the material buffer, leading to potential losses, collisions, and uneven loading, which affect the overall operational efficiency and effectiveness of the system.
Innovation Solution
The rock processing apparatus utilizes a control unit to ascertain a target subarea within the overall feed area based on detection signals and operating parameters, allowing for precise and optimized material feeding within the material buffer, even out asymmetrical loads, and enhance the performance of downstream units like screening and crushing apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If material is fed into the material buffer without targeted location control, then the feeding process is simple and fast, but the material distribution becomes uneven and causes asymmetrical loads
Solution Approach 1:
The patent applies local quality by dividing the material buffer into different target subareas and feeding material to specific locations based on detected material levels. The control unit identifies underfilled subareas and directs the loading apparatus to deposit material precisely in those regions, ensuring uniform distribution while maintaining efficient feeding operations.
2Loss of substance
If the bucket is positioned precisely over the material feeding apparatus, then material is fed without loss, but the positioning system becomes more complex
Solution Approach 1:
The patent implements feedback by using sensors to detect the fill level of the material buffer and providing this information to the control unit. The control unit then calculates the optimal target subarea and communicates this to the loading apparatus control, creating a closed-loop system that reduces material loss without requiring overly complex positioning hardware.
3Device complexity
If material is fed continuously without location optimization, then the feeding process is simple, but downstream units experience uneven loading and reduced efficiency
Solution Approach 1:
The patent applies preliminary action by proactively detecting material levels in different subareas of the buffer before feeding occurs and pre-calculating the optimal target location. This advance planning ensures that material is deposited where it is most needed, preventing downstream units from experiencing uneven loading and maintaining high efficiency throughout the processing system.
