Mobile Crusher Bucket with Integrated Screen and Magnet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile jaw and impact crushers lack efficient mechanisms for separating and processing materials by size and removing metal contaminants, which hinders their effectiveness in construction and demolition sites.
Innovation Solution
Integration of a screen and/or magnet attached to the crusher's bucket, allowing for size-based material separation and metal removal, with the screen being vibratable and orientable to manage material flow and the magnet being self-cleaning to handle metal contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a screen is added to the crusher bucket for size-based material separation, then material processing efficiency is improved, but device complexity increases
Solution Approach 1:
The screen is integrated directly into the crusher bucket structure, merging the crushing function with the screening function into a single unified device. This eliminates the need for separate screening equipment and reduces overall system complexity despite adding size separation capability.
Solution Approach 2:
The crusher bucket is designed to perform multiple functions: crushing material and simultaneously separating it by size through the integrated screen. This multi-functionality improves material processing efficiency without requiring additional dedicated equipment.
2Reliability
If a magnet is added to the crusher bucket for metal contaminant removal, then material purity is improved, but device complexity increases
Solution Approach 1:
The magnet is integrated into the crusher bucket structure, merging the crushing function with the metal separation function into a single unified device. This eliminates the need for separate metal detection and removal equipment.
Solution Approach 2:
The crusher bucket is designed to perform multiple functions: crushing material and simultaneously removing metal contaminants through the integrated magnet, ensuring material purity without requiring additional dedicated equipment.
3Productivity
If the screen is made vibratable for better material flow management, then material separation efficiency is improved, but use of energy increases
Solution Approach 1:
The screen is designed to vibrate during operation, using mechanical vibration to facilitate material flow and improve separation efficiency. The vibration helps prevent material buildup on the screen and ensures consistent size-based separation.
4Reliability
If the magnet is made self-cleaning for continuous metal removal, then material purity is maintained, but device complexity increases
Solution Approach 1:
The magnet is designed with self-cleaning capability, allowing it to automatically remove accumulated metal contaminants without requiring manual intervention or complex external cleaning mechanisms. The crusher operation itself facilitates the cleaning process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances material processing efficiency by creating separate size-based flows and effectively removing metal contaminants, improving the overall performance and waste reduction capabilities of mobile crushers.
Implementation Method 1
Vibrating and/or orienting the screen can be implemented in a number of ways, including so as to generate at least two separate flows determined by the size of the material exiting the outlet of the bucket
Implementation Method 2
a magnet attached to the crusher's bucket, which can be attached to a piece of construction equipment... Provision also can be made for removing metal attracted to the magnet
