(4)Check that there is no foreign body at the outlet
2.Running
Screw conveyor should be no-load operation after starting,the handling material can be added when screw conveyor is running normally.Keep feeding uniformly.
Prevent iron accessories and foreign material from entering the screw conveyor during the process of operation.
Operator shall check if the oil level of reducer is normal,keep the transmission parts lubrication.Make sure anchor bolts of bearing are fastened.
3.Stop running
Make sure all of the material is discharged befor screw conveyor stops,load jobs must be banned.
Several sets of screw conveyor formed a conveyor line,stopping procedure shall be contrary to running procedure.
Press the button “emergency stop” of the control box when parking and maintenance

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
