4. Noise, severe vibration

(1) Cause of failure:

①The bearing is damaged;

②Serious wear of the ring molding roller;

③The gap between the ring die and the pressure roller is too small;

④There are foreign objects in the conditioner or feeder;

⑤The spindle bearing is too loose.

(2) Elimination method:

①Replace the bearing;

②Replace the mold roll;

③ Properly increase the gap between the mold rolls;

④Clean up foreign objects;

⑤Tighten the nut to reduce the clearance.

5. Unreasonable fluctuation of host load or uneven particle quality

(1) Cause of failure:

①The steam supply of the steam pipe is insufficient or the pressure changes from time to time;

②The raw material transportation is unstable;

③The scraper of the deflection plate is worn out causing uneven feeding.

(2) Elimination method:

①Check the steam pipeline;

②Adjust the feeding speed;

③Replace the deflector scraper.

6. The ring die chicken feed pellet making machine stops during work

(1) Cause of failure:

①The tension of the V-belt is not enough to make the speed controller move;

②The speed control instrument parameter setting is unreasonable;

③ Part or all of the V-belt is severely worn or broken;

④The main shaft rotates due to overload or impurities stuck between the pressure roller and the ring die, and the travel switch falls off;

⑤The pressure of the hoop is not enough, or the brake disc is slipped with grease, which causes the main shaft to rotate and the travel switch is released;

⑥ The line is faulty.

(2) Elimination method:

①Re-adjust the tension of the V-belt or check the pressure value on the pressure gauge of the hydraulic system. If necessary, reset the pressure value (be careful when adjusting);

②Reset its parameters;

③Install a new set of V-belts, not just a part of them can be replaced;

④Reset the spindle and travel switch;

⑤Reset the hydraulic pressure of the hoop or clean the brake disc;

⑥Check the line.

7. The ring die chicken feed pelleting mahcine is often blocked

(1) Cause of failure:

①Uneven distribution of materials worn by the deflection scraper;

②The pressure roller is worn;

③The pressing rollers on one by one are stuck;

④The assembly position of the deflection scraper is wrong;

⑤The feed water content is too high.

(2) Elimination method:

① Replace with a new deflection scraper;

② Replace with a new pressure roller;

③Check the pressure roller;

④ Reassemble the deflection scraper;

⑤Reduce the moisture content.

8. The temperature rise of the spindle head is too high

(1) Cause of failure:

The spindle bearing clearance is too small.

(2) Elimination method:

Properly loosen the compression nut.

9. Safety pin cut off

(1) Cause of failure:

Hard foreign matter enters the granulating chamber.

(2) Elimination method:

Remove foreign objects and replace safety pins.

10. The motor current difference is too large

(1) Cause of failure:

① The V-belt of the second motor is not tensioned;

②The balance fine-tuning of the second motor is uneven;

③The quality of the ammeter.

(2) Elimination method:

①Tighten the belt or replace the belt;

② Level the motor;

③Replace or adjust the ammeter.

11. Smoke from the chicken poultry feed pellet granulator mill

(1) Cause of failure:

①The scraper is worn, so that a hard material layer is formed between the pressure roller and the rotor support plate;

②The V-belt tension is not enough;

③The hard materials are piled up between the supporting plates behind the pressing roller to form a hard material layer.

(2) Elimination method:

① Install a new scraper;

②Tighten the V-belt;

③Remove hard materials and lubricate the main bearing until the grease emerges from the back of the rear support plate.

12. Every time the chicken feed pellet press rotates, a ticking sound is heard

(1) Cause of failure:

There are metal impurities in the ring die.

(2) Elimination method:

Check the inner surface of the ring die and remove metal impurities.

13. V-belt slips when fully loaded or slightly overloaded

(1) Cause of failure:

① The tension of the V-belt is not enough;

②The length of the V-belt in the same group is inconsistent;

③The V-belt is stained with grease;

④ The position of the V-belt is incorrect;

⑤The shape of the V-belt is wrong.

(2) Elimination method:

①Tighten the V-belt as required;

② Replace the entire set of belts of the same brand;

③Clean the V-belt and pulley;

④ Correct the motor and intermediate pulley;

⑤ Use qualified V-belts.

14. The output of the pellet manufacturing mahcine for chicken feed is insufficient, and the main motor is fully loaded

(1) Cause of failure:

① Due to excessive addition of steam (only refers to materials that are particularly sensitive to temperature and humidity);

②Because the ring die is too thick;

③Due to poor steam quality and high water content;

④The material is not sufficiently quenched and tempered;

⑤The gap between the pressure roller and the ring die is too large;

⑥Excessive wear of pressure roller and ring die;

⑦The formula is not good or the crushing particle size is too large

(2) Elimination method:

①Small steam should be added;

②The thickness of the ring die suitable for the material should be used;

③The gas supply system should be readjusted;

④Increase the amount of steam added or extend the conditioning time;

⑤Re-adjust the gap;

⑥Replace the pressure roller and ring die;

⑦Adjust the formula or replace the sieve with small aperture.

15. The ring die breaks after being worn to a certain extent

(1) Cause of failure:

① There are foreign bodies in the laminated film;

②A ring die that is too thin is used;

③There is a problem with the fixing of the ring die.

(2) Elimination method:

① The cleaning of materials should be improved;

②Use thicker ring dies with stepped holes;

③Check whether the drive rim of the ring die and the fastening bolts are locked, and replace the drive rim if necessary.

③Using improper grease;

④The lubricating grease of the pressure roller is added too little;

⑤Use the damaged bearing end cover and sealing ring;

⑥Used roller bearings of poor quality produced by other manufacturers.

(2) Elimination method:

①Improve material cleaning;

② Correctly adjust the gap between the pressure roller and the ring die;

③Use grease according to regulations;

④Add enough grease as required;
