Necessary steps for keeping pellet mill in good condition

1. Adding oil to front main bearing every 2 hours; adding oil to transmission part every 4 hours to ensure granulating machine transmission part of the flexible rotation, reduce the work load.

2. Keep regular replacement of lubricating oil in the gear box of the granulator, after a new machine running half a month after, take replacement of oil, after each work for about 1000 hours must be replaced once. Only in this way can prolong the service life of the gear.

3. Every week carefully check all parts of connection parts, if safety switch operation reliable. At the same time, the cleaning feeding auger and conditioner, avoid the occurrence of mechanical fault.

4. Each and a half months to check the transmission key and the pressure of the lining wear and tear, and found that the wear and tear in a timely manner to avoid shaking and affect the yield of the ring.

5. Using high quality ring mold, press roller. The circle and an inner hole rough inferior ring mode to eliminate the use of, and according to the different formulations selected ring die compression ratio and guarantee the ring die smooth material, to avoid the increased power consumption and reduced capacity.

6. Adjust the ring die and press roll gap. If the machine occurs, it is necessary to loosen the pressure roller, remove the ring die inner wall material after the re adjustment of the die roll gap, absolutely cannot be forced to start, to avoid causing the transmission parts and bearing gear due to severe vibration and damage.

7. To eliminate excess load production. Production process cannot exceed the granulator itself can withstand the ability to work, or will occur motor damage and parts of the accelerated wear and shorten the service life of the granulator.

8. Raw materials must be do a good job of removing iron impurity removal work, each class clean up an iron removing device, to avoid foreign body into the ring die studio, fuselage vibrations and cracking of the ring die phenomenon.

Structure and working principle of YONGLI pellet mill

YONGLI ring die pellet mill is mainly composed of feeding, conditioning, granulation, transmission and lubrication system etc. Its working process requires the powder water content is not more than 15%. Powder from the hopper into the feeding auger, by adjusting the infinitely speed motor speed to obtain appropriate material flow, and then enter the conditioner, and through further stirring rod stirred and mixed with steam quenching and tempering. If you need to add molasses or grease, from conditioner joined together with steam conditioning, adding amount of fat is generally not more than 3%, otherwise difficult to shape). After quenching and tempering, the temperature of the powder mixture can reach 64 to 85 degrees C and the humidity is 14 to L 6%. And then through the chute through suction device of iron powder to remove iron impurities mixed in, and finally into the press room. Ring die pelletizer suppress room main working parts by ring mode, two roller, feeding blade, cut knife ...

Pellet mill ring die inspection and adjustment.

Yongli ring touch lining ring wear the ring die and the transmission wheel is hollow shaft is concentric, that is, we often say ring concentric die is not good, will also enable Yongli machinery granulator produces vibration capacity decreased, seriously affect the service life of the ring die and Yongli machinery granulating machine, can also cause: "ring guide die mouth or a draw ring die cracking and fragmentation; increase mechanical granulating machine spindle bearings and air shaft bearing and gear shaft and the keys of the load to accelerate the wear and tear"; Inspection method: Caliper: wear a 0.5 mm, should be replaced; the ring die is arranged in the driving wheel and ring mold flange and a transmission wheel relative deviation of the observed; ring die and the driving wheel assembly asymmetric ring mold sagging, up, down, left and right push the ring die not loose feeling.
