Split End Wall Roller Crusher Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machinery frames for roller crushers face difficulties in easy removal of crushing rolls due to tilting end walls and the need to disassemble other rolls during maintenance, leading to complex reassembly and potential material and dust leakage.
Innovation Solution
A machinery frame design with horizontally and vertically split end walls, where the upper parts do not touch, allowing for easy removal of a roller without tilting, and sealed gaps to prevent material and dust exit, using connecting elements like flat steel plates and screw connections for stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the end wall upper part is made removable to facilitate roller removal, then the ease of repair is improved, but the end wall upper part tilts during removal making the process difficult
Solution Approach 1:
The end wall is divided into three distinct segments: the lower part remaining fixed, the upper part that is removable for maintenance, and a newly introduced middle part that acts as a connector. This segmentation allows the upper part to be removed independently without tilting, as the middle part provides stable support during the removal process.
Solution Approach 2:
The middle part of the end wall serves as an intermediary element between the fixed lower part and the removable upper part. During roller removal, this middle section acts as a mediator that prevents the upper part from tilting, providing a stable transition zone that facilitates easy and controlled removal.
2Ease of operation
If the side walls are loosened to create more space for removing the end wall, then the ease of operation is improved, but a multitude of contact surfaces must be cleaned during assembly
Solution Approach 1:
By segmenting the end wall into distinct parts (lower fixed part, middle connector part, and upper removable part), the invention eliminates the need to loosen side walls. The middle part provides sufficient clearance on its own, allowing the upper part to be removed without affecting the side wall assembly or requiring extensive surface cleaning.
3Adaptability or versatility
If the end wall is divided to allow single roller removal, then the adaptability is improved, but elements of the other roller must still be disassembled
Solution Approach 1:
The end wall segmentation allows each roller to be accessed and removed independently. The middle part of the end wall provides a dedicated removal path for one roller at a time, eliminating the need to disassemble the other roller's elements. This segmented design creates isolated access zones for each roller.
4Stability of the object's composition
If the cowl top parts are separated to prevent tilting, then the stability of the object's composition is improved, but material and dust can exit through the gap
Solution Approach 1:
The cowl top parts are segmented into separate sections with intentional gaps between them. This segmentation prevents the parts from touching and tilting relative to each other, while the gaps are designed to accommodate sealing elements that prevent material and dust leakage.
Solution Approach 2:
Sealing elements are introduced as intermediary components between the separated cowl top parts. These seals fill the gaps created by the segmentation, preventing material and dust from escaping while allowing the cowl parts to remain separated and stable.

AI summary
The present invention relates to a machine frame for a roll crusher that has two side walls and two end walls, where the mentioned end walls accommodate the storage of the rolls. The end walls are split horizontally in the area of the mounting of the rollers, and vertically between the mountings of the upper part. One advantage is that to remove a roller, removal of the respective upper end wall is sufficient. In a preferred embodiment of the invention, the adjacent upper parts of the end walls do not touch. An advantage of this is that tilting of the end wall upper parts among each other or in contact with the side walls is prevented during removal. Furthermore, the gap resulting from the distance between the front wall upper parts in the preferred embodiment would be sealed, with the advantage that no material and dust can exit.
