Condition of failure | Cause (in processing) | remedy |
|
---|
Insufficient flow rate | foreign matter in feed valve. | remove the foreign matter | worn iron screw | replace the worn part | worn emery roller | replace the worn part | worn huller blade | replace the worn part |
|
A large amount of worn milling roller | a large amount of broken rice | check the material condition | excessive flow rate | decrease the flow rate to reduce the load | excessive weight resistance | decrease the weight resistance | worn huller blade | replace the worn part |
|
A large amount of broken rice | a large amount of cracked grains | decrease the flow rate to reduce the load | excessive weight | adjust weight | worn huller blade | replace the worn part |
|
Rice temperature rise too high | insufficient air flow rate | increase the air flow rate | inferior efficiency of screen, emery roller due to wear down | replace the worn part | adhesion of bran to screen frame or clogging thereof | remove the bran stuck on the frame or on the apertures |
|
Inferior separation of bran | insufficient air flow rate | increase the air flow rate |
