Operation & maintenance of YONGLI hammer mill

YONGLI hammer mill feeding operation should be uniformed, can not be erratic, ensure the motor at rated load. Opening the free door is prohibited in the production process. In the normal production process, opening any coupling guards is forbidden.
    Grinder during operation if unusual noise or blocked discharge, bearings or motor overheating, should stop feeding, cut off the power, check until the rotor stops, troubleshooting. After the work is completed, must be idle for 2 minutes, the machine crush the material completely discharged before being shut down. Instead shutdown and startup sequence. After the shutdown of the mill be down to check, identify problems promptly resolved. It must be cleaned of magnetic impurities mill entrance magnetic board.
    YONGLI hammer mill arranged symmetrical arrangement form, hammer when installed, must be in strict accordance with the arrangement, and the corresponding hammer weight difference of the two groups can not be more than 5 grams. After sharp blunt hammer, you can use a reverse angle adjustment (reversing every day can achieve hammer simultaneously wear two sharp corners). If the hammer two sharp corners are worn, they should use a U-turn. When a U-turn, should hammer all at the same time, to keep the balance of the rotor. After the corners are worn, replace them with new hammer, which arrangement should be strictly in accordance with the instructions of, and each hammer weighed. In the hammer wear late due to uneven wear, so out of balance grinder, vibration intensified, this time should be corrected rotor static balance, reassembled or replaced with new hammer hammer. Sieve size should be based on the requirements of crushed material to choose the appropriate mesh sieve. It should be replaced after sieve wear or damage. Installation screen films, sieve with a burr in the side should be, smooth outwards, screen films and screen frame are linked closely together.
   Mill maintenance should be strictly in accordance with the rules to operate, the class must make the necessary checks. You should always check on the cotter pin, if excessively worn or broken, replace it immediately. It should be regularly inspected, cleaned (100 hours) and lubricate the bearings. Machine parts found severe wear and damage should immediately repair and replacement of the rotor after the repair should be balancing test. Class after work, both inside and outside the machine should be cleaned to remove dust and dirt in order to avoid rusting machinery, sieve clogged inner bearing into the dirt.

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.
