Rotating spiral chute —— Let every grain of mineral sand "run" towards high-grade products by itself

#Industry ·2026-03-15

It's not just a chute, but a "thinking" re-concentration production line. The rotating spiral chute integrates three gravity fields (centrifugal, gravitational, and shear) into a spiral. The mineral slurry gently falls from the top, initiating a high-speed sorting marathon with an accuracy of 0.02 g: - The 360-degree rotating disc superimposed with 9-ring variable-pitch channels increases recovery by up to 28%; - The patented composite cross-section allows heavy minerals to "stick to the wall" rather than "stick to impurities", boosting grade by 5–12 percentage points; - Power-free automatic layering consumes 0.7 kW·h per ton, saving enough electricity to power a magnetic separator annually; - Integrally molded from fiberglass, it requires no major overhauls for three years, withstands pH 1–14 corrosion, and even resists rust in coastal titanium mining; - Modular assembly adds one ring in 5 minutes, allowing throughput to scale freely from 2 t/h to 80 t/h. Whether it's beach zirconium and titanium, fine tailings from tungsten and tin, or "gold mining" from smelting slags, it turns 0.02 mm precision into profits by exploiting density differences as small as 0.001 g/cm³.

Enter the ore density and target grade, and it'll provide the optimal number of rings and slope in 30 seconds, enabling lab-scale testing directly on-site. The rotating spiral chute makes sorting as simple as water, and profits as spiraling as its design.
