Tungsten, known for its exceptional hardness and high melting point, is a critical metal in various industrial applications ranging from cutting tools and electronics to aerospace components. The primary source of tungsten is scheelite (CaWO₄), a calcium tungstate mineral that requires efficient processing to extract the valuable metal. The grinding phase is particularly crucial as it determines the liberation degree of tungsten minerals from the gangue, directly impacting recovery rates and production efficiency.
European mining operations face unique challenges in scheelite processing, including stringent environmental regulations, energy efficiency requirements, and the need for consistent product quality. Modern grinding technology must address these concerns while maintaining operational reliability and cost-effectiveness.
Scheelite beneficiation typically involves crushing, grinding, and concentration processes. The grinding stage is particularly critical because:
Traditional grinding approaches often fall short in meeting the specific requirements of scheelite processing, particularly in achieving the narrow particle size distribution necessary for efficient tungsten recovery.
Shanghai Zenith Machinery Co., Ltd., as an excellent manufacturer of ore grinding equipment, has developed specialized solutions for challenging minerals like scheelite. Our extensive research and development in ultra-fine powder grinding technology have yielded equipment specifically suited for tungsten production facilities.
For European scheelite processing operations, we highly recommend the MTW Trapezium Grinding Mill. This advanced grinding system incorporates multiple patented technologies that make it ideal for tungsten production:
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110 | <30 | 1.6-0.045 | 3-9 | 55 | 55 |
| MTW110Z | <30 | 1.6-0.045 | 3-10 | 55 | 55 |
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 | 110 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 | 200 |
| MTW215G | <50 | 1.6-0.045 | 15-45 | 280 | 315 |
The MTW series offers several advantages for scheelite grinding:
For operations requiring ultra-fine grinding of scheelite concentrates or specialized tungsten products, the LUM Ultrafine Vertical Mill represents the cutting edge of grinding technology:
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) |
|---|---|---|---|
| LUM1525 | 220-250 | 1.6-11.5 | 5-30 |
| LUM1632 | 280-315 | 2.0-13.5 | 5-30 |
| LUM1836 | 355-400 | 2.3-15 | 5-30 |
