Ⅶ Cautions:
1 Before starting the machine, turn the belt pulley manually to see if it is blocked.
2 Before starting the machine, tightening all connecting screws, especially the three screws on internal wear sleeve inside heating tube.
3 Before stopping the machine after continuous work, empty the hopper first, and run it reversely for one minute, then the machine can be stopped.
4 When work begin again, the machine can‘t be started before the temperature of heating tube rises to 350℃;charge a little material first, after stick is produced, you can charge at large quantity.
5 When working, pay attention to the voltage and the electricity current to see if they are normal to avoid motor damage.
6 When the propeller can’t rotate, stop the machine at once, run it reversely, clear the material in the hopper, and raise temperature again. After the temperature is 20℃ higher, start the machine again and follow the above proper steps.
7 The product outlet should be pointed to a wall and a plank should be put in front of it against wall.
8 When you begin to work, no person should stand in front of the outlet !!!
9 Electric circuits should be kept dry and clean, after stopping the machine, power must be turned off.
10 Stone and iron chips are strictly forbidden to get into hopper. As soon as any abnormal phenomenon appears stop the machine at once.
11 All lubricating parts must be oiled every two months and always checking if there are leaking of oil.
12 It is forbidden to start the machine without the machine being well grounded.
TECHNOLOGY OF REPAIRING PROPELLER
After working for 24 hours, propeller should be checked, if it is worn, it should be taken down and repaired.
When any of the following conditions appears, it needs to repair the propeller.
1 The speed of producing sticks has obviously decreased.
2 Machine often clogged and can’t work well even if the humidity of the material and temperature are proper as specified,.
3 machine can produce briquette, but the briquettes can’t integrated into a complete stick, it is broken into small and short briquette pieces.
4 Briquettes produced quickly, but in bad density.
5 The front end of propeller is worn less than 4mm.
6 The internal diameter of the product sticks is less than 15mm.
7 Because of stone, nail, or other foreign matter going into propeller or other reason, the spiral part of the propeller is worn.
REPAIRING PROPELLER
1 Preheat the end part of the propeller which need surfacing temperature must reach 350℃.
2 Use special welding rod and AC welding machine, adjust electricity to about 150A-240A (It depend on the electric current to the welding rod).
3 Do surfacing by layer according to the condition that the front angle of the propeller end is worn. After each layer, remove the welding slag before next layer. Surfacing thickness must be 1-2mm thicker than the needed thickness. After surfacing, there should be no such shortcomings as slag insertion, gas holes, etc.
4. After surfacing, insert that part into warm keeping materials (such as calcium oxide, plant ash etc.) to cool gradually, the inserted depth must be the length of minimum three screws.
5. When it is cooled to 50 degree or below, takes it out and grind on green silicon carbide emery wheel to the correct angle. Please be careful in this process and it is forbidden to make individual part too hot, or cool with water or other liquid.
6. When grinding, the front angle increase by 2 degrees at end of each screw 360 degree , and gradually reach 22 degree +/-1.5 degree at the end of front angle. During the increasing of the front angle in this process, there should be no bumps or hollows, unsmoothness or defects.
7 As is shown in above picture, if the 105mm long circumference of the end of propeller is worn more than 6mm, the propeller need to be repaired according to following technology.
(1) After preheating according to the technology stated above, do surfacing at the 105mm long circular surface with J442 carbon welding rod. Surfacing thickness should be 1—2mm thicker than the size marked in above picture(convenient for later grinding).
(2) Insert it into dry quick time or farm plant ash to cool, and grind it according to the size marked in the picture when it is cooled to 50℃ or lower. The increasing amount shouldn’t exceed 2mm, and there should be no obvious hollows or protruding.
8 It is strictly forbidden to strike or knock at the repaired propeller to avoid the damage of the surfacing or other part. It should be stored carefully for future use.
APPENDIX B
Grinding special propeller
1 Repairing propeller as shown in the above picture, the welding repair method refers to appendix A.
2 The width of the second protruding spiral is half of the original width.
3 The second protruding spiral starts at the point that turns 90°from the end part (this is for special raw material that is difficult for briquetting).
