Ⅴ Installation and test
1 Tightening all connecting screws, especially the three screws on internal wear sleeve inside heating tube. Connecting the temperature sensor on the heating tube (thermal couple) and all electrical parts and wires.
2 Check all lubricating parts.。
3 Check power voltages to ensure they are normal.
4 Start and run for 10 minutes without feeding raw material. If there isn’t abnormal phenomenon such as block or bump, you can begin to work with the machine. If you find any abnormal phenomenon, stop the machine at once, inspect the machine carefully, and solve the problem before running it again without feeding.
5 Adjust the temperature regulator to the requested temperature. Only after temperature reaches the requested temperature point, can you start the machine and feed in raw material properly.
6 Gradually increase the feeding amount of raw material until qualified product is produced. Normal working for 30 minutes shows the test is successful, and then you can go into normal production.
7 Before stopping the machine, empty the charging hopper, and run it in reverse direction for one minute to make the material in propeller come out.
8 The machine must be installed on a flat ground to avoid shaking while working!
| No. | Phenomenon | Cause | Repairing methods |
| 1 | Power indicator doesn’t light. |
(1)Wire not connected.
(2)Fuse is spoiled.
(3)Indicator spoiled |
(1) Connecting wire properly.
(2)Change new fuse.
(3)Change new indicator |
| 2 | Motor can’t be started. |
(1)Control knob spoiled.
(2) Two phase running
Wrong Voltage or frequency |
(1)Change new knob.
(2)Connecting wire properly.
Check the voltage and frequency. |
| 3 | When heating, temperature rise very slow or can’t reach specified temperature |
(1)Power voltage is too low.
(2)Heating collar is spoiled.
When you change electrical heating line of the heating ring, line of wrong type was used. |
(1) Check the voltage.
(2) Change the heating collar.
（3）Change according to the requirement. |
| 4 |
Motor is hot.
|
(1)Loading too much material.

stator winding or Short circuit between phases. |
(1)Check according No .5.
(2)Check fuse, switch, contact point, fix the breakdown.
(3)Change the bearing.
(4)Clear the path.
(5)Decrease the temperature.
(6)Adjust the voltage.
Check and fix the breakdown according |
| 5 | Stick can’t be produced |
(1) Material is too wet.
(2)Heating temperature is too low.
(3)Spiral groove is blocked.
(4)The groove in the internal sleeve of heating tube and the groove in heating sleeve are in relatively wrong place.
(5)Voltage is too low.
(6)Internal wear sleeve is broken.
Propeller is worn. |
(1)Dry the material.
(2)Raise the temperature.
(3)Grind propeller and remove obstacle.。
(4)Install the internal sleeve of heating tube again.
(5)Check voltage
(6)Repair or change inner wear sleeve
(7)Repair or change propeller.
|
| 6 | Sticks can’t be formed |
(1)Material is too wet.
(2)The spiral groove in the internal sleeve of heating tube and that in heating sleeve is relatively not in right place.
(3)Temperature is too high.
(4)The front angle of the propeller is less than 20℃.
(5)Thermal couple is fixed in wrong place or not properly.。
(6)Heating ring is in short circuit.
Too much oil in the material. |
(1)Dry the material to requested moisture content.
(2)Install the internal sleeve of heating tube again.
(3) Decrease the temperature.
(4) Grind the front angle.
(5)Fix the thermal couple well.
(6)Check the circuit of the heating ring.
Improve the front angle of the propeller(refer to appendix 2) |
| 7 | Steam coming out from the hopper or bombing |
(1)Material too wet.
(2)Stand internal sleeve is badly worn.
(3)Internal sleeve of heating tube is badly worn.
Spiral front angle of the propeller doesn’t accord with the demands |
(1)Dry the material to requested moisture content
(2)Repair the sleeve.
(3)Repair the sleeve.
Grind the propeller. |
