INDUSTRY BREAKING NEWS After 3 years of intensive R&D and 12 months of industrial field validation, Jiangxi Yituo Mining Equipment (YTO) today officially launched the world’s first “Vortex-Enhanced” high-efficiency spiral chute. This product achieves a major breakthrough in the long-standing global industry challenge of “low fine-grained mineral recovery”. Without increasing energy consumption or floor space, it raises the average recovery rate of -0.037mm fine-grained minerals from the traditional 45% to over 67%, and improves overall mineral processing efficiency by 30%, completely rewriting the technical landscape of gravity separation.
Industry Pain Point: The “Fine Particle Recovery Dilemma” Plaguing Global Mining
For decades, fine-grained (-0.037mm) mineral recovery has been the technical bottleneck in gravity separation. Traditional spiral chutes have extremely poor separation effects on fine particles due to unstable flow fields and insufficient stratification, resulting in more than 10 million tons of valuable metal minerals being lost with tailings worldwide every year. The iron ore industry alone suffers economic losses exceeding 20 billion RMB annually.
Many mining companies have had to adopt costly flotation processes to recover fine-grained minerals, which not only increases mineral processing costs by 30%-50% but also brings serious environmental problems.
YTO’s Core Technological Breakthroughs: Three Innovations Disrupt Traditional Design
The YTO technical team, in collaboration with the Mineral Processing Engineering Research Center of China University of Mining and Technology, has overcome multiple key technical challenges through thousands of laboratory tests and industrial optimizations:
Vortex-Enhanced Flow Field Technology
Original “variable pitch + variable cross-section” spiral trough design creates a stable vortex stratification zone inside the trough
Enables fine-grained heavy minerals to quickly enrich toward the inner edge of the trough, significantly improving separation accuracy
Nano Wear-Resistant Lining Technology
Adopts self-developed nano-ceramic composite wear-resistant material
Service life is 2.5 times longer than ordinary fiberglass linings, reaching more than 5 years
Intelligent Regulation System
Equipped with intelligent feeding and automatic flushing devices
Can adjust operating parameters in real time according to ore properties, always maintaining the best separation state
Industrial Validation: Stunning Actual Production Data
The new generation spiral chute has undergone 6 months of industrial production verification at a large tungsten mine in Ganzhou, Jiangxi, and the Ghana iron ore project in Africa, achieving remarkable results:
| Parameter | Traditional Spiral Chute | YTO Next-Gen Spiral Chute | Improvement |
| -0.037mm Tungsten Ore Recovery | 42% | 65% | +23% |
| -0.037mm Iron Ore Recovery | 46% | 68% | +22% |
| Overall Comprehensive Recovery | 72% | 83% | +11% |
| Unit Processing Energy Consumption | 0.8kWh/t | 0.75kWh/t | -6% |
| Equipment Service Life | 2 years | 5 years | +150% |
“We originally planned to invest 8 million RMB to build a new flotation workshop to recover fine-grained tungsten ore,” said Li Jianguo, Director of the Mineral Processing Plant of Ganzhou Tungsten Mine. “After using YTO’s new generation spiral chute, we achieved the same recovery effect with only 1.2 million RMB. We also save more than 1.5 million RMB annually in reagent and labor costs, with an investment payback period of less than 10 months.”
Industry Expert Evaluation: A Milestone Breakthrough in Gravity Separation Technology
Professor Zhang, Dean of the School of Mineral Processing Engineering at China University of Mining and Technology and Ph.D. supervisor, stated: “The successful development of YTO’s new generation spiral chute is one of the most important breakthroughs in gravity separation technology in the past 30 years. It not only greatly improves the recovery rate of fine-grained minerals but also provides a low-cost and environmentally friendly mineral processing solution for many small and medium-sized mines, which will have a profound impact on the development of the global mining industry.”
The Secretary-General of the Mining Machinery Branch of China Heavy Machinery Industry Association pointed out: “This technology breaks the monopoly of foreign enterprises in the high-end mineral processing equipment field, marking that China’s mining machinery manufacturing has entered the ‘leading’ stage from ‘following’.”
Market Impact: Redefining Industry Standards
With the official launch of the new generation spiral chute, YTO has received more than 50 intentional orders from over 20 countries and regions worldwide. The company plans to achieve mass production in the second half of 2026 with an annual capacity of 500 units.To reward new and existing customers, YTO specially launches the
