Cone Crusher Protection With Continuous Feed Diversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile crushing machines face inefficiencies and reduced throughput due to the need to completely stop the feed conveyor and remove undesirable metallic materials from the aggregate feed, which can damage the crusher device.
Innovation Solution
A system and method that detects undesirable metallic materials in the aggregate feed using a detector, and diverts the feed away from the crusher device using a movable diverter chute, allowing the conveyor to continue operating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the feed conveyor is completely stopped to remove undesirable metallic material, then the crusher device is protected from damage, but the operating efficiency and throughput of the crushing system are reduced
Solution Approach 1:
The system segments the feed conveyor operation into two paths: a main path that continues transporting aggregate material and a diverted path that directs material away from the crusher when metallic contaminants are detected. This allows the conveyor to remain operational while protecting the crusher, resolving the contradiction between continuous operation and equipment protection.
Solution Approach 2:
The diverter mechanism acts as an intermediary between the feed conveyor and the crusher device. It selectively redirects material flow based on detector signals, enabling the system to protect the crusher without stopping the conveyor or completely removing material, thus maintaining throughput while ensuring reliability.
2Reliability
If the feed conveyor is completely stopped to remove undesirable material, then the metallic material can be removed from the feed, but the operating efficiency of the mobile crushing system is reduced
Solution Approach 1:
The system dynamically adjusts the diverter mechanism's position based on real-time detector signals. When metallic material is detected, the diverter automatically redirects material flow; when the conveyor stops, the diverter directs material to the bypass chute. This dynamic operation allows the system to maintain ease of operation while protecting the crusher.
Solution Approach 2:
The feed conveyor continues to operate continuously at normal speed, transporting aggregate material without interruption. The diverter mechanism handles the protection function, allowing the main conveyor operation to remain continuous and efficient while still protecting the crusher device from damage.
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
Prevents damage to the crusher device by diverting undesirable materials without stopping the feed conveyor, thereby maintaining operational efficiency and throughput.
Implementation Method 1
one or more metal detectors is positioned somewhere along the feed conveyor to detect the presence of a metallic material in the feed of the aggregate material

AI summary
A crushing machine that includes a crusher device fed by a feed conveyor for processing a feed of aggregate material. A detector is positioned along the feed conveyor to detect the presence of an undesirable material, such as a portion of metallic material. Upon detection of the undesirable material, a diverter is moved from a first mode to a second mode to divert the feed of material away from the crusher device. Once the detected undesirable material is no longer present in the feed of material, the diverter is returned to the first mode after a delay to direct the feed of aggregate material back to the crusher device. The operating speed of the feed conveyor is not adjusted during the movement of the diverter. The diverted feed of aggregate material is directed to a discharge chute located away from the infeed end of the crusher device.
