| 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 |
