Common problems and solutions of Shandong Dingxin DXCS-200 strong coarse crusher:

1、 Crushing chamber jamming or shutdown

Phenomenon: Material blockage leads to equipment jamming or automatic shutdown.

Solution: Immediately turn off the power and clean the foreign objects in the crushing chamber, check if the material size exceeds the standard (it is recommended to control it below 3-5cm); Adjust the feeding speed to ensure uniform feeding; Regularly clean up residual materials to prevent accumulation.

2、 Abnormal high temperature of bearings

Phenomenon: The bearing temperature exceeds the safety threshold during operation.

Solution: Supplement or replace lubricating oil that meets the standards (recommended food grade grease), clean clogged oil nozzles; Check the installation levelness of the bearing seat and correct the deformed pad iron; If the bearing shows rust, cracks, or abnormal noise (such as' rustling 'sound), it should be replaced with a new bearing in a timely manner.

3、 Body vibration or abnormal noise

Phenomenon: The body shakes violently or makes abnormal noise during operation.

Solution: Tighten the foundation bolts and rotor connecting components to reinforce the stability of the foundation; Check if the rotor shaft is bent (pressure correction is required if it exceeds 0.2mm); Correct the coaxiality between the motor shaft and the rotor shaft; Remove metal foreign objects from the crushing chamber.

4、 Decreased crushing efficiency

Phenomenon: The particle size of the discharged material becomes coarser or the yield significantly decreases.

Handling: Repair/replace worn teeth or blades; Adjust the gap between the crushing chambers to the equipment calibration value; Check the tightness of the triangular tape, tighten or replace it if it is too loose; Confirm voltage stability to avoid low voltage causing insufficient power.

5、 Hydraulic system oil leakage

Phenomenon: Oil leakage occurs at the sealing point or pipeline joint.

Solution: Replace aging or damaged seals; Re tighten the hydraulic pipeline joints; Regularly clean the hydraulic oil filter to prevent blockage and abnormal pressure.

Key points of daily maintenance

Clean the residual materials in the crushing chamber after each shutdown;

Check the lubrication status of bearings and the integrity of seals every week;

Monthly testing of rotor balance, bolt tightness, and foundation stability.

By standardizing operations and preventive maintenance, the failure rate can be reduced. If encountering complex mechanical damage, it is recommended to contact the manufacturer for professional repair.
