Introduction
The YTO-LL series spiral chute is a new generation of gravity separation equipment independently developed by Jiangxi Yituo. Adopting the original Vortex-Enhanced Flow Field Technology and Nano Wear-Resistant Lining, it achieves a major breakthrough in the long-standing challenge of fine-grained mineral separation. Widely used in the beneficiation of gold, iron, ilmenite, tin, tungsten and many other ores, it features high processing capacity, excellent recovery rate, stable operation and low energy consumption, making it the preferred equipment for gravity separation operations in mining enterprises worldwide.




Core Advantages
✅Industry-Leading Separation Efficiency
- Original variable pitch + variable cross-section spiral trough design creates a stable vortex stratification zone
- Improves -0.037mm fine-grained mineral recovery by 22% and overall comprehensive recovery by 11%
- Increases beneficiation efficiency by 30% without additional energy consumption or floor space
✅ Exceptionally Long Service Life
- Features thickened fiberglass matrix + self-developed nano-ceramic composite wear-resistant lining
- Service life is 2.5 times longer than ordinary fiberglass spiral chutes, reaching over 5 years
- Corrosion and impact resistant, adaptable to various harsh mining environments
✅ Modular and Flexible Design
- Available in single, double, triple and quadruple start configurations to meet different processing capacity requirements
- Spiral trough inclination and cross-section shape can be customized according to ore properties
- Easy installation and maintenance, can be freely combined into multi-stage separation systems
✅ Intelligent Operation Control
- Optional intelligent feeding and automatic flushing systems
- Real-time monitoring of operating status, automatic parameter adjustment to maintain optimal separation performance
- Reduces manual operation intensity and human error
Working Principle
A spiral chute separates mineral particles based on density differences under the combined action of gravity, centrifugal force and water flow friction. Ore pulp is fed from the upper end of the spiral trough and moves in a spiral motion along the trough surface. Denser mineral particles gradually migrate toward the inner edge of the trough, while lighter gangue moves toward the outer edge. They are finally collected separately through interceptors at different positions, achieving efficient mineral separation.
