Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and more specifically, to a crusher toothed roller. Background Technology

[0002] In toothed roll crushers, the toothed rolls are typically one-piece, meaning the roll teeth are fixedly welded to the roll shaft. After prolonged use, the toothed rolls need to be disassembled for repair to extend their service life. Currently, disassembly requires removing the entire toothed roll. However, since the roll rotates within the crusher and is connected to the motor shaft via a coupling, disassembly necessitates removing multiple components, a time-consuming and labor-intensive process. Alternatively, some toothed rolls have the roll teeth fixedly welded to multiple tooth plates, which are then bolted to the roll shaft. Repairing these plates simply involves removing them from the shaft, but this method involves numerous bolts, resulting in lengthy and inefficient disassembly. Utility Model Content
