Interchangeable Ring Grinding Tool Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinding devices require frequent shutdowns and tool replacements due to mechanical stress and adaptation to varying materials, leading to increased production downtime and costs.
Innovation Solution
The use of interchangeable rings that allow for the simultaneous replacement of grinding tools without interrupting the grinding operation, with the load removal function handled by a softer steel ring and the grinding tools made of wear-resistant materials, enabling longer tool life and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grinding tools are frequently replaced due to wear and material adaptation, then tool functionality is maintained, but shutdown time increases
Solution Approach 1:
The grinding tool is divided into two separable parts: the interchangeable ring (carrier) and the grinding segments. The ring remains mounted on the support disk during operation, while only worn or inappropriate segments need replacement. This segmentation allows segments to be changed independently without removing the entire tool assembly, significantly reducing shutdown time while maintaining reliable grinding functionality.
Solution Approach 2:
Multiple grinding segments can be pre-mounted on spare interchangeable rings outside the grinding device. When tool changes are needed, pre-prepared rings with appropriate segments are quickly swapped into position. This preliminary preparation of replacement components eliminates time-consuming on-site tool assembly operations and minimizes production downtime.
2Duration of action of moving object
If grinding tools are made of hard wear-resistant material, then tool life is extended, but manufacturing cost increases
Solution Approach 1:
The invention treats grinding segments as replaceable, relatively inexpensive components that can be worn out and replaced. The segments are made of wear-resistant material to extend their service life, but when they wear down, they are simply replaced rather than requiring replacement of the entire expensive tool assembly. The interchangeable ring serves as a reusable carrier that amortizes its cost over many segment replacements.
Solution Approach 2:
By segmenting the grinding tool into reusable ring and replaceable segments, the system allows selective replacement of only the wear-prone segments. This reduces the frequency of replacing high-value components and spreads the manufacturing cost over a longer operational period, effectively extending tool life while controlling manufacturing expenses.
3Adaptability or versatility
If individual grinding segments are fastened separately, then adaptability to different materials is achieved, but installation and removal expense increases
Solution Approach 1:
Multiple grinding segments are merged onto a single interchangeable ring that is pre-assembled outside the grinding device. This combination allows the entire ring with multiple segments to be handled as one unit during installation and removal, significantly reducing the complexity and expense of installation operations while preserving the ability to adapt to different materials by selecting appropriate segment configurations.
Solution Approach 2:
The interchangeable ring with its segments is prepared and assembled in advance outside the grinding device. This preliminary assembly eliminates the need for complex on-site installation procedures, reducing both time and expense. The pre-assembled ring can be quickly swapped into position, maintaining material adaptability while simplifying the installation process.

AI summary
A device for grinding input material is provided with a supporting disk rotating around an axis of rotation within a housing. On the supporting disk, in its circumferential area, first grinding tools are arranged concentrically, axially opposite from which second grinding tools are arranged, forming a radial grinding gap. During operation of a device in accordance with the invention, the grinding tools execute a motion relative to one another. In accordance with an embodiment, the first grinding tools be fastened over an interchangeable ring to the supporting disk, wherein the interchangeable ring is fastened removably to the supporting disk concentric to the axis of rotation and on which the first grinding tools are arranged.
