Feed mill granulator safety operation procedures

(1) Check and debug Pg4 China feed industry information network before starting up - based on feed, service animal husbandry

1. Adjust the position of the cutter away from the ring touch, open the granulator door, and replace the ring mold according to the need to clean the scale, iron filings and other debris in the pressing chamber; check whether the fixing bolts of the hoop bolt and the pressure roller are tightened; Whether the gap of the die roll (about 0.1-0.3mm) is suitable, under the driving of the ring die, it can be turned into a non-rotation; whether the position of the scraper is in place; the movable parts are rotated by hand to ensure that they are not caught.

2. Fill the lubrication parts with lubricating oil according to the lubrication diagram. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

3. Check the permanent magnet cylinder, feeder, and conditioner, and do not have any debris such as hemp rope or iron filings; start the feeder and adjust the air conditioner to ensure the correct running direction, no abnormal sound; feeder Stop at low speed. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

4. Drain the condensate from the cylinder and check that the pressure gauge shows normal. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

5. Start the main motor (this operation is mainly suitable for the newly installed machine or the machine after the line transformation, under normal circumstances, it is not allowed to open the door), to ensure that all running parts in the granulator are working properly, to ensure that the ring mold is clockwise from the front. Rotating, the surface of the pressure roller is in micro contact with the inner surface of the ring mold, and it is driven by the ring mold to achieve a non-rotation. Stop after correct. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

6. Close the door and adjust the cutter so that the gap of the die (not less than 3 mm) meets the needs of the production products of this class. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

(2) Pelletizing production Pg4 China feed industry information network - based on feed, serving animal husbandry

1. Start the equipment of the granulator after the process. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

2. Start the main motor of the granulator. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

3. Start the conditioner motor. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

4. Start the feeder motor. The electromagnetic speed regulating motor is adjusted to a low speed, so that the feed slowly enters the tempering machine and the granulator pressing chamber. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

5. When the granulation is just started, do not add steam, and slowly increase the feed rate of the feeder according to the main motor current. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

6. Open the steam valve slightly, wait for the main motor current to drop, and then increase the feeding amount appropriately so that the main motor current is close to the normal load, then increase the steam amount to lower the main motor current. This is repeated until the main motor produces the highest output at rated load and the pellet quality is best. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

7. Ensure that the granulator current runs within the rated current and must not be overloaded. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

(3) Stopping the machine Pg4 China feed industry information network - based on feed, serving animal husbandry

1. Turn off the steam and feeder (the interval between the two is as small as possible). Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

2. Let the granulator continue to run until the granules stop forming. Then turn off the temper. If the machine needs to stop working for a while, add the oily powder to the manual feeding port until the granules are formed. If it is off work or long down, the inner hole of the ring mold should be filled with oil. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

3. Turn off the main motor. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

4. Cut off all power after work. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

(4) Precautions Pg4 China Feed Industry Information Network - Based on feed, serving animal husbandry

1. During the production process, when the material entering the granulator is too much, causing the current to rise suddenly, the manual discharge mechanism must be used for the discharge outside the machine. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

2. When the granulator door needs to be opened, the power must be cut off before the granulator can be completely stopped before the door can be opened. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

3. When restarting the granulator, the granulator must be turned by hand (one turn) before the granulator can be started. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

4. When the machine fails, the power must be cut off, and the machine must be shut down. It is strictly forbidden to carry out hard elimination by hand, foot, wooden stick and iron in operation; it is strictly forbidden to start the motor hard. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

5. When using the new ring mold for the first time, it is necessary to use a new pressure roller, which can be mixed with fine sand (all passed through a 40-20 mesh sieve, the ratio of material: oil: sand is about 6:2:1 or 6: 1:1) Rinse the ring mold for 10 to 20 minutes and put it into normal production. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

6. Assist the maintenance worker to check the main motor bearing for 1 time every year. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

7. Assist the maintenance worker to change the lubricating oil gearbox to the granulator gearbox 1-2 times a year. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

8. The permanent magnet cylinder should be cleaned at least 2 times per shift. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

9. The steam pressure entering the jacket of the conditioner is not higher than 1kgf/cm2. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

10. The steam pressure entering the conditioner is in the range of 1-4kgf/cm2 (normally not less than 2.5 kgf/cm2). Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

11. Add 2-3 times to the pressure roller for each shift. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

12. Clean the feeder and conditioner 2-4 times a week (clean up once a day in summer). Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

13. The distance between the cutter and the ring die is generally not less than 3 mm. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry

14. During normal production, it is strictly forbidden that the main motor current exceeds the rated current, that is, overload operation. Pg4 China Feed Industry Information Network - based on feed, serving animal husbandry
