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 ...
