Adjustable Material Guide for Crushing Plant Oversize Chute
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crushing plants face inefficiencies due to oversize grains circulating in an endless loop, causing unnecessary stress on the screen unit and reducing machine performance.
Innovation Solution
An adjustable material guiding element is introduced for the oversize grain chute, allowing operators to change the material guide area, enabling oversize grains to bypass or partially bypass the screen unit, thereby optimizing machine operation and preventing or reducing endless loop circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the screen unit screens all oversize material, then classification precision is improved, but the screen unit becomes overloaded and machine performance deteriorates
Solution Approach 1:
The patent extracts a portion of the oversize material flow from the screen unit by providing a bypass channel that directs selected oversize grains directly to the crushing unit without passing through the screen. This reduces the load on the screen unit while maintaining classification precision for the material that does pass through screening.
Solution Approach 2:
The patent implements an adjustable material guiding element that can dynamically redirect oversize material between the screen unit and the bypass channel based on operational requirements. This dynamic adjustment allows optimization of screen unit loading and overall machine performance under different operating conditions.
2Productivity
If the adjustable material guiding element redirects oversize material to bypass the screen unit, then the burden on the screen unit is reduced, but classification precision may be compromised
Solution Approach 1:
The patent applies different processing paths to different portions of the material flow: selected oversize grains are directed through the bypass channel while other material continues through the screen unit. This local differentiation allows the system to optimize screen unit performance for specific material portions without compromising overall classification accuracy.
3Adaptability or versatility
If the material guiding element is made adjustable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent incorporates an adjustable material guiding element within the oversize grain chute that can be positioned to direct material flow differentially. This dynamic adjustment capability provides operational flexibility while the element remains integrated within the existing chute structure, limiting the increase in overall device complexity.
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
This solution enhances machine performance by reducing the burden on the screen unit, preventing endless loop circulation of oversize grains, and allowing for optimized material guidance, leading to improved processing efficiency.
Implementation Method 1
a return conveyor (80) which is designed and arranged to convey oversize material coming from the crushing unit (40) by means of its discharge end (82) onto an oversize grain chute (27) to direct the oversize material to the material feed area
Implementation Method 2
at least one adjustable material guiding element (28) is assigned to the oversize grain chute (27), wherein with the adjustable material guide element (28) the machine operator can decide how he wants to design the material guide area of the oversize grain chute (27)
Implementation Method 3
A screen unit can be arranged in the area of the material feed device, which is arranged in front of the crushing unit in the direction of material flow. The screen unit has at least one screen deck. The material to be crushed can be classified on the screen deck.
