Wood pellet mill motor operation precautions

YONGLI sawdust pelleting machine motor operating supply voltage and rated voltage deviation is not more than + 5%, unbalanced three-phase voltage does not exceed 1.5%. Motor running current shall not exceed the rated current on the brand name, three-phase current imbalance of not more than 80%, otherwise it will cause the motor fever and even burn. YONGLI granulator with thermometer, use thermometer to measure the motor casing surface temperature should not exceed 80 DEG C, bearing temperature should not exceed 95 DEG C, the motor should be keep clean, dry, well ventilated, air inlet and the air outlet will frost kept clear. Running in the motor appear smoke, violent vibration, abnormal sound, special smell, speed decreased significantly; load equipment failure; the occurrence of shock should be immediately shut down.

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 ...
