Still using fixed chutes to "wait for the ore to flow away"? The new generation of rotating spiral chutes turns gravity concentration into a "centrifugal force" high-tech solution! 360-degree spin vortex with a recovery rate of 30%, ensuring that even the finest gold and tungsten-tin particles won’t escape! Frequency-controlled speed adjustment allows switching between three modes (coarse selection—fine selection—sweep selection) in just one minute, eliminating the need for two separate devices! Modular 1-meter units can be powered up and used immediately. Old processing plants can complete the upgrade in 30 minutes with zero downtime! Waterless ore discharge reduces circulating water by 70%, enabling direct operation in arid plateaus and Gobi desert mining areas! Urethane one-piece molding ensures 3-year wear resistance without patching, saving 80,000 yuan in annual consumables costs per unit! Place your order now and receive a dual gift package of "wear-resistant spare parts + installation and debugging" (limited to the first 50 orders)—the money is flowing, but the opportunities are fleeting! Don’t miss out!
