If the conveyor regularly operates under heavy loads, consider upgrading to a motor with higher power. Poor heat dissipation: Clean off any dust and debris from the motor surface to ensure the cooling vents are clear. Avoid running the motor in high-temperature environments for too long. Jammed bearings: Inspect the bearings for wear and tear. Apply fresh grease, and replace them immediately if they are damaged. Wiring faults: Check the electrical connections for loose wiring or aging cables. Repair or replace the damaged wiring right away.
• Q：What should I do if the screw conveyor leaks material during operation?

  A：Material leakage is usually caused by seal failures or structural wear. Check these three areas to fix it: Damaged seals: Inspect the trough seals and O-rings. Replace any aging or broken sealing components immediately to restore a tight seal. Trough or blade wear: Check for holes or thinned areas on the trough walls and screw flights. Repair or replace the worn sections right away, and set up a regular inspection schedule. Inlet/Outlet leaks: Adjust the sealing mechanisms at both the feeding inlet and discharge outlet. Install extra gaskets or sealing pads to stop materials from escaping.
