Project Background:

For a long time, China’s iron ore industry has been grappling with outdated beneficiation technologies, low concentrate grades, and widespread losses or near‑loss conditions among most mining enterprises. Leveraging its extensive grinding expertise, Changsha Wanrong Powder Equipment Technology Co., Ltd. established a research team dedicated to the ultrafine recovery of iron concentrates and developed a vertical multi‑axis ultrafine energy‑efficient mill.

Changsha Wanrong Powder Equipment Technology Co., Ltd. is a specialized manufacturer of ultrafine grinding machines and powder‑modification equipment. Its core products include the cell‑grinding wet‑process ultrafine grinder and the honeycomb‑grinder continuous powder‑modification machine. Notably, its multi‑axis grinder series has achieved significant technological breakthroughs in the field of metal‑ore beneficiation.

Project Configuration:

Ball mill One unit, one vertical multi-axis ultra-fine energy-saving grinder.

Core Data Comparison:

Before beneficiation: Iron grade 58.07% iron, 3.03% sulfur; after beneficiation: iron grade 70.74%, sulfur 1.89%. Production capacity: 30,000–50,000 tons per month; production cost: 40 yuan per ton; monthly profit exceeds 3 million yuan.

Technical features:

Feed particle size 0–3 mm; discharge particle size adjustable from 350 to 2000 mesh. Single-unit capacity: 100 tons/hour, with energy consumption reduced by 40%. Compact footprint (a 4‑m diameter is sufficient), simple foundation requirements, and easy installation. Recovery rate reaches 99.8%, with low water usage, no encapsulation, no entrainment, and no tailings carryover.

Conclusion:

After modification, the quality of the iron concentrate surpasses that of imported ore, making it suitable for producing specialty steels and enabling the manufacture of high-value-added products such as magnetic materials and sponge iron. The vertical multi‑axis ultrafine energy‑saving mill demonstrates significant techno‑economic advantages in the grinding and beneficiation of both metallic and non‑metallic ores.
