Rotating spiral chute: Let every grain of mineral sand "run out" by itself to achieve high-quality output

#Industry ·2026-03-24

It's not just a simple chute, but a three-dimensional channel that "squeezes out" wealth. The rotating spiral chute integrates gravity, centrifugal force, and laminar shear into a single spiral line. As soon as the ore slurry enters, heavy and light minerals automatically stratify, with a concentration ratio that is more than 30% higher than traditional chutes and a recovery rate that starts at 15% higher. With a diameter of 1 meter and a footprint of just 0.8 square meters, it can complete three processing stages—coarse sorting, fine sorting, and sweeping sorting—in a single device. All parameters, including rotational speed, water volume, and inclination angle, are fully controlled by PLC. For tungsten, tin, gold, and coastal placer deposits... just adjust the settings to target the specific minerals you want to recover. The wear-resistant polyurethane lining lasts for 5 years without replacement. Modular assembly allows expansion in just 30 minutes with only three people. Space constraints in the processing plant? Budget limitations? Stack the rotating spiral chutes vertically to double processing capacity and cut infrastructure costs in half. 68 mines have tested this solution: with the same daily processing capacity of 500 tons, the concentrate grade has increased by 3.2 percentage points, resulting in annual cost savings of 4.2 million yuan. Contact us now to receive free process simulations and sand sample tests. The first 50 orders will also include a smart feeding controller to maintain optimal "gold-digging curves" 24 hours a day. The rotating spiral chute Lets the ore run itself, while you earn money effortlessly.
