Crushing Roll Support Disk for Tool Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crushing rollers require complete replacement or complex reconfiguration of crushing tools to change their position, which is time-consuming and costly, limiting flexibility in adjusting the crusher's feed behavior.
Innovation Solution
A crushing roller design featuring a detachable support disk with a cylindrical shape and axial length that can be adjusted, allowing for variable positioning of crushing tools without replacing the entire roller, using a tongue and groove connection for torque transmission and threaded holes for secure fastening, enabling easy configuration changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If crushing tools are arranged in crushing shells that are detachably connected to the crushing roller, then maintenance time and costs are reduced, but the configuration of the crushing roll cannot be changed without replacing the entire roll
Solution Approach 1:
The crushing roller is segmented into modular components: a roller body, detachable crushing shells, and a support disk with repositionable connection means. This segmentation allows the crushing shells to be replaced independently while maintaining the ability to reconfigure the overall tool arrangement by changing the support disk position or configuration.
Solution Approach 2:
The support disk incorporates movable or repositionable connection means that allow dynamic adjustment of the crushing shell positions. The connection means can be moved to different locations on the support disk, enabling the configuration of the crushing roller to be changed without replacing the entire roll assembly.
2Device complexity
If the crushing roller is designed as a one-piece unit, then structural simplicity is maintained, but the entire roll must be replaced when crushing tools wear out
Solution Approach 1:
The one-piece roller design is segmented into a roller body and detachable crushing shells. This allows the crushing shells to be replaced independently when worn, avoiding the need to replace the entire roller assembly and reducing both cost and complexity of maintenance.
Solution Approach 2:
The detachable crushing shells can be removed and replaced separately from the roller body. The worn crushing shells are discarded and replaced with new ones, while the roller body and support disk are retained and reused, optimizing resource utilization and reducing waste.
3Ease of repair
If crushing tools are inserted into openings in the crushing roller, then tool replacement is simplified, but the positions of crushing tools cannot be changed without replacing the roll
Solution Approach 1:
The support disk incorporates movable connection means that allow dynamic repositioning of the crushing shells. The connection means can be moved to different locations on the support disk, enabling the positions of crushing tools to be adjusted without replacing the entire roll, while still allowing for simple tool replacement when needed.

AI summary
According to the invention, at least one support plate is arranged between the crushing shells and the shaft, in a removably connected manner thereto. According to the invention, the support plate is designed to have a cylinder shape. A support plate according to the invention has means for removable connection to a shaft in the cylinder interior and means for fastening crushing shells on the outer cylinder surface. The axial length of a support plate is dependent on the specific application case. In the simplest case, there is a support plate which bears all crushing tools of the crushing roll. However, a plurality of support plates can also be arranged axially adjacent to each other. The configuration of the crushing roll can be advantageously changed by replacing the support plate(s). It is thus possible to change the configuration of the crushing roll via a relative change of the circumferential position of the means for removable connection to a shaft in the interior of the support plate relative to the circumferential position of the means for fastening the crushing shells to the outer surface. The infeed behavior of the crusher can thus be advantageously and simply changed without replacing the entire crushing roll.
