AI Technical Summary
The discharge port size of existing jaw crushers is inconvenient to adjust, making it difficult to adapt to changes in material characteristics. Furthermore, they are prone to blockage due to material jamming, which affects crushing efficiency and continuity.
The distance between the moving plate and the fixed plate is adjusted by a bidirectional screw driven by a motor, which enables flexible adjustment of the discharge port size. The push plate breaks up the material jamming state and prevents blockage.
It achieves flexible adaptation and anti-clogging of the discharge port, improves the adaptability and continuity of the crusher, and reduces downtime losses.
