Operating a cone crusher requires proper knowledge of its components, safety protocols, and maintenance procedures to ensure efficiency and longevity. Below is a step-by-step guide to cone crusher operation:
—
1. Pre-Operation Checks
Before starting the cone crusher:
– Inspect the crusher: Check for wear/damage on liners, mantles, concaves, and other components.
– Lubrication: Ensure the lubrication system is working (oil levels, filters, and pumps).
– Hydraulic system: Verify pressure settings and check for leaks.
– Belt tension & drive components: Ensure belts and couplings are properly aligned.
– Feed material: Remove oversized or uncrushable objects (e.g., metal) to avoid damage.

2. Starting the Cone Crusher
1. Warm-up the crusher (if cold): Run the empty crusher for a few minutes to circulate oil.
2. Start the lubrication system first (if separate from the main drive).
3. Engage the main drive motor gradually (avoid sudden starts).
4. Check for abnormal noises or vibrations.

3. During Operation
– Feed material evenly: Avoid overloading or “starvation” (uneven feeding causes uneven wear).
– Monitor discharge size: Adjust the closed-side setting (CSS) as needed for product size.
– Watch for tramp metal: Use metal detectors or magnets to prevent damage.
– Check oil temperature & pressure: Abnormal readings may indicate issues.
– Avoid “ring bounce”: Caused by excessive feed or incorrect settings.

4. Adjusting Settings
– Closed-Side Setting (CSS): Adjust hydraulically or mechanically to control product size.
– Smaller CSS = finer output but reduced capacity.
– Larger CSS = coarser output but higher throughput.
– Speed & stroke settings: Optimize for material type (hard rock vs. soft ore).

5. Shutdown Procedure
1. Stop feeding material first.
2. Let the crusher run empty briefly to clear remaining material.
3. Turn off the main drive motor.
4. Keep the lubrication system running for a few minutes to cool bearings.

6. Maintenance Tips
– Regularly inspect liners and replace when worn (~50% remaining life).
– Check oil filters and change them as recommended by the manufacturer.
– Monitor belt tension and alignment
