The Common Mistake: “Won’t the Water Tank Catch the Aluminum?”<\/h2>\n\n\n\n
Many beginners ask: “Can’t my water floating tank separate aluminum?”<\/em><\/p>\n\n\n\n The short answer is: No, it can’t.<\/p>\n\n\n\n Water separation works purely on density:<\/p>\n\n\n\n In a standard complete PET bottle washing line<\/a>, the screw auger at the bottom of the tank scoops up the PET flakes and the aluminum together, dumping both directly into the \u30db\u30c3\u30c8\u30a6\u30a9\u30c3\u30b7\u30e3\u30fc<\/a>.<\/p>\n\n\n\n When this mixed plastic enters the extruder at 280\u00b0C, the PET plastic turns into liquid melt, but the aluminum stays solid (aluminum doesn’t melt until 660\u00b0C). As the screw spins, it drags these hard metal chunks against the barrel wall like nails on a blackboard. The result? A deeply scratched barrel, leaking plastic, ruined filter screens, and an emergency shutdown of your rPET pelletizing line.<\/p>\n\n\n\n Since magnets cannot pull aluminum, Shuliy Machinery uses a smart machine called an eddy current separator for plastic.<\/p>\n\n\n\n Instead of pulling metal like a magnet, this machine shoots aluminum forward like a catapult.<\/p>\n\n\n\n Here is how it works in plain language:<\/p>\n\n\n\n Timing is everything. You cannot separate aluminum when the plastic is still wet, because water makes the flakes stick together.<\/p>\n\n\n\n Shuliy’ s engineered layout places metal removal in three logical checkpoints:<\/p>\n\n\n\n\n
