AI Technical Summary
In the existing technology, ordinary measuring tools are difficult to insert between the rollers of a twin-roll crusher and accurately position them, which makes the measurement time-consuming and laborious and makes it difficult to ensure the consistency of the measurement points.
A tooling for detecting the gap between two roll crushers was designed, including a fixing component and a measuring component. Through the cooperation of the pressing component and the measuring component, the gap between the crushing rolls can be automatically measured, and the stability of the measurement position is ensured by locking bolts and ratchet mechanism.
It enables simple and stable measurement of the gap between crushing rollers, is easy to operate, and can automatically retain the measurement position, thus improving the accuracy and consistency of the measurement.
