Common troubles & solutions

Common troubles Causing reasons Solutions
Material overflow The sundries in the material will clog up hanger shaft. Stop running and remove the sundries
The material stick to blade or shaft because of high moisture Moisture control when feeding,

clean the blade in time

Circumventing of transmission device Stop running and repair it
The jam of outlet Check the outlet and downstream equipment,keep clear
Material amount is superior to design value Material amount controlling
Equipment shell instability When installation,the center line of spiral segment is different Fine the correct center line when re-installation
Driving motor overload Sundries in the handling material Prevent iron accessories from entering the screw conveyor;

Space maintenance between screw blade and shell

Too large feeding capacity will results in motor overload Control feeding capacity
The jam of outlet Check the outlet and downstream equipment,Keep clear
Too much stock before stop Make sure all of the material is discharged befor screw conveyor stops
