Common faults include material blockage, unstable discharge, abnormal noise, excessive wear, bearing problems, motor overload, and leakage around the inlet, outlet, or cover.
What can cause screw conveyor motor overload?
Motor overload can be caused by overfeeding, material blockage, high material resistance, worn or bent screw flights, unsuitable conveyor angle, or material buildup inside the conveyor.
How can screw conveyor faults be reduced?
Use a suitable conveyor size and speed, control the feed rate, inspect wear parts regularly, keep the discharge clear, and match the conveyor design to the material properties and installation angle.
