The spiral chute is not a "trough", but a "VIP fast lane" for ore - turning it into concentrate in seconds while the waste rock slips away on its own! 1 inclined spiral, 0 motors, 0 tons of reagents. Relying on gravity, heavy minerals cling to the wall and fly out, while light waste rock is thrown to the outer circle. The sorting accuracy is 30% higher than that of the jig machine, yet it consumes 100% less electricity. Can't "catch" gold, tungsten, and tin particles as small as 0.3 mm? We reduced the groove spacing to 4 mm, boosting recovery rates by 18% and making tailings visibly clearer. The entire machine weighs 200 kg and can be set up by two people in 10 minutes; modular inserts allow for a 1-layer height increase in 3 minutes, instantly doubling processing capacity without increasing plant budgets but maximizing returns. The wear-resistant layer has a hardness of 62 HRC. Even after 24 hours of feeding, 365 days of operation, the chute surface remains "scratch-free" after 5 years. Downtime for maintenance? None at all! Place an order now and receive a pair of "flow calibration discs". Match the concentration in just 5 minutes on-site, boosting recovery rates by an additional 5%. Don't let ore "overnight" in old equipment - let it slide into the spiral chute! Mine today, count money tomorrow!
