Breakedown of Pellet Mills ? YONGLI offers solutions.

YONGLI machinery as a manufacturer of particle machine, has professional R & D team and production of pellet machine equipment. According to the industry, many customers in the process of using particle machine may encounter granulating machine noise and abnormal situation, YONFLI summarized the following reasons:
1, if a part of a granulating machine bearing breaks down, the machine is not operating properly, the working current will fluctuate. High operating current (stop check or replace the bearing).
2, ring mode blocking, or only part of the die hole output material. Ring mode in the entry of foreign matter, ring die round loss, pressure roller and die gap is too tight, pressure and wear or roller bearing damage cannot be rotation will produce granulator (check or replace the die ring vibration, adjust the pressure roller clearance).
3, coupling imbalance correction, about the level of deviation, granulating opportunity vibration and gear shaft oil seal is easy to damage couplings must school to a horizontal line).

4, the spindle is not tightened, especially D type or E type machine, spindle looseness will produce axial traverse back and forth, the pressure and the obvious swing, granulating machine noise big vibration, granulating difficulty (tightening spindle end butterfly spring and a round nut).
5, the size of the gear wear, or the replacement of a single gear, it will produce noise (need to run time).
6, from the outlet of the conditioner under non-uniform material, make the job of granulating machine current fluctuation (need to adjust the conditioner blade).

7, the use of new ring mold must be equipped with a new roller, and a certain proportion of sand chaff for grinding, polishing after use (to eliminate the use of inferior ring mode).
8, strict control of quenching and tempering time and temperature, keep abreast of into the machine, raw water, the raw material that is too dry or too wet will cause discharging is not normal, granulator abnormal.
9, steel frame structure is not solid, granulating machine to work in the steel frame vibration, granulating machine is easy to produce and reinforcing steel structure resonance (must be.
10, the rear end of the quenching and tempering device is not fixed or fixed to produce shaking (need to be strengthened).
11, granulating machine leakage reasons: seal wear, the level is too high, bearing damage, coupling unbalance, vibration of the fuselage, start forcibly.

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 ...
