Comminution Machine Impact Rocker Gap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crushing machines are limited in their ability to handle diverse types of feed materials, particularly steel-reinforced concrete, leading to frequent component failures and high downtimes due to the high strength of the material and issues with impurities, which require manual intervention for removal, posing safety risks and increasing costs.
Innovation Solution
A shredding machine with an impact rocker device and a screening device, where the impact rocker is adjustable relative to the rotor, allowing for adjustable gaps to facilitate the passage of comminuted material and easy removal of impurities, and featuring a rotor with interchangeable blow bars and impact tools for universal comminution capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional crushing machines with fixed hammers or blow bars are used, then they can handle specific types of feed material, but they suffer from frequent component failures when processing high-strength materials like steel-reinforced concrete
Solution Approach 1:
The rotor is designed with interchangeable components - blow bars can be replaced with impact tools depending on the feed material being processed. This dynamic reconfiguration allows the machine to adapt to different material types (high-strength concrete requiring impact tools vs. softer materials suitable for blow bars), thereby improving reliability by selecting the appropriate tool for each material type rather than using fixed components that may fail
Solution Approach 2:
The rotor assembly serves multiple functions by accommodating both blow bars and impact tools on the same rotor structure. This universal design allows a single machine to handle diverse feed materials including steel-reinforced concrete, eliminating the need for separate machines for different material types and improving overall system reliability through proper tool selection
2Ease of operation
If manual intervention is used to remove impurities from the crushing chamber, then impurities can be removed, but safety risks increase and downtimes extend
Solution Approach 1:
The impact rocker is designed to be automatically adjustable relative to the rotor, allowing the gap between them to be modified without manual intervention. This self-adjusting mechanism enables the system to handle impurities and maintain operation automatically, eliminating safety risks associated with manual entry into the crushing chamber and reducing downtime by avoiding complete shutdowns for impurity removal
3Adaptability or versatility
If the gap between the impact rocker and rotor is fixed, then the structure is simple, but it cannot accommodate different feed material sizes and impurities
Solution Approach 1:
The impact rocker is designed with adjustable positioning relative to the rotor, allowing the gap size to be dynamically modified based on feed material characteristics and impurity presence. This dynamic adjustment capability enables the system to accommodate various material sizes and clear impurities by enlarging the gap when necessary, while maintaining a relatively simple structural design through straightforward adjustment mechanisms
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
The machine can handle a wide range of feed materials with reduced component failures and downtimes, enabling efficient comminution of steel-reinforced concrete and other materials while minimizing safety risks and operational costs through adjustable settings and easy maintenance.
Implementation Method 1
A comminution of feed pieces takes place essentially by means of the hammers by impact, comminution by impact of the feed pieces taking place by means of the edges or impact bars of the rotor
Implementation Method 2
crushing machines without rotatable hammers are regularly referred to as impact crushers and have cutting edges or edges, which also bring about a comminution of a feed material fed to the comminution machine
Implementation Method 3
Feed material fed into the shredding chamber through a feed chute falls onto the rotor, among other things, and is thrown by the blow bars onto the impact rocker in accordance with the direction of rotation of the rotor and crushed by impact
Implementation Method 4
The impact rocker itself can, among other things, be spring-mounted and suspended from a fixed rocker bearing in the crushing room
