Spiral chute: an efficient and energy-saving solution, and a smart choice for gravity mineral processing

#Industry ·2026-03-04

In the field of mineral sorting, the pursuit of high efficiency, low consumption, and environmental protection has always been the core goal. The spiral chute, as an outstanding representative of this pursuit, has become an indispensable tool for many mineral processing plants with its unique gravity sorting principle. What is a spiral chute? A spiral chute is a powerless gravity sorting device that utilizes differences in the specific gravity, size, and shape of mineral particles to achieve effective mineral sorting within a spiral trough through the combined effects of gravity, centrifugal force, and friction in the mineral slurry. It has a simple structure and is easy to operate, making it an ideal choice for processing fine and ultra-fine minerals. Core Advantages, Creating Value for You 1. High-Efficiency Sorting, Striving for Excellence: The spiral chute accurately captures minerals with different specific gravities, achieving high recovery rates and high-grade concentrate. Whether it's coarse sorting, scavenging sorting, or fine sorting, it can deliver excellent sorting results, maximizing resource utilization. 2. Energy-Efficient and Environmentally Friendly, a Green Future: Without any power drive, the sorting process is completed entirely by water flow and the mineral slurry's own gravity. With zero energy consumption and zero emissions (referring to no chemical reagents), it greatly reduces operating costs and meets the stringent requirements of modern industry for green mining and sustainable development. 3. Simple Structure, Easy Maintenance: With no moving parts, it greatly reduces mechanical failure rates and prolongs equipment lifespan. Daily maintenance only requires paying attention to water flushing and wear and tear, which saves effort and significantly reduces labor and maintenance costs. 4. Small Footprint, High Processing Capacity: The unique spiral structure enables high-efficiency mineral slurry processing within a limited space. For processing plants with limited site space or those seeking to increase unit area production, the spiral chute is undoubtedly an ideal solution. 5. Wide Applicability, Multifunctional: It is widely used in the sorting and refining of various heavy minerals such as iron ore, titanium iron ore, chromite, zircon, rutile, monazite, tin ore, tantalum-niobium ore, gold ore, and coal, as well as the coarse sorting and scavenging sorting of non-ferrous metals, rare metals, and non-metallic minerals. Working Principle, Enabled by Technology The mineral slurry is evenly fed from the feeder above the chute and moves downward along the spiral trough under gravity. Due to the slope of the spiral trough, the mineral slurry generates self-flow and rotational motion within the trough. Mineral particles with higher specific gravity are subject to less centrifugal force and friction, making them more likely to settle and move inward under gravity; while lighter particles are carried outward by the water flow and eventually discharged. By appropriately adjusting the width, slope, and water flushing parameters of the trough, different minerals can be effectively separated.
