1The crusher part clmping ring assembly is a key fixing device for the cone crusher, including clmping rings, hydraulic ring clamping set, dust covers, and other accessories. It is mainly used to prevent the bowl assembly from rotating spontaneously due to vibration during crusher operation, ensuring stable discharge port dimensions and thus guaranteeing the crusher's working efficiency.
Installation location: Installed between the adjusting ring and the lower frame.
Material: Steel.
Applicable Scenarios: Suitable for spring & hydraulic cone crushers: medium-fine crush granite, basalt, iron ore, limestone & C&D waste; for aggregates, mining, stone processing, building materials & metallurgy.

FAQ
1. Is it possible to replace just a single component instead of the entire assembly?
Yes, individual components such as clamping rings, hydraulic rings, dust covers, and fasteners are available separately. However, if a clamping ring shows cracks or the threads are severely worn, replacing the entire assembly is recommended to ensure reliable locking performance.
2. What should I do if the pressure won't build up?
Check for hydraulic leaks or seal degradation → Check threads for foreign matter or damage → If everything is normal, the threads are severely worn and need replacement.
3. Do you support custom production for non-standard models?
Yes, we do. We can manufacture custom products based on your drawings, samples, or crusher model specifications.
