What is daily maintenance for a jaw crusher?

The jaw crusher is a core piece of crushing equipment in industries like mining and construction. Its stable operation directly impacts production efficiency. Routine maintenance not only reduces downtime due to failures but also significantly extends the equipment's service life.

Pre-Startup Inspection

1. Check the tension of the V-belt, jaw plate, and the tightness of all bolts.
2. Inspect the equipment casing and frame for cracks and loose bolts.
3.  Check the oil level in the hydraulic tank to ensure it is between the oil gauge lines. Check the hydraulic quality and verify that the hydraulic pump is operating properly and that there are no leaks in the oil pipes.
4.  Clear any remaining material from the feed inlet to avoid stalling during startup. Check the discharge opening clearance to ensure it meets production requirements to prevent substandard crushing or equipment overload.

Inspection During Operation

1. Bearing temperature is within the normal range.
2. The tie rod spring is normal.

Regular Maintenance After Shutdown

1. Lubricate every 40 operating hours.
2. Lubricate the discharge opening adjustment device and inspect the rubber cover (for mechanical adjustment of the discharge opening).
3. Inspect the cheek plates for wear and replace if necessary.
4. Check the toggle plate for alignment, straightness, and cracks.
5. Inspect the toggle plate seat and rubber seal, and clean the toggle plate seat surface if necessary.
6. Check the tightness of the frame mounting bolts.
7. Inspect the flywheel.
8. Inspect the rubber shock absorber pads for wear.
