Top 4 Best multi gravity separator manufacturers 2026
In the modern era of mineral processing, the recovery of fine and ultrafine particles has become a critical priority for mining operations worldwide. As traditional gravity methods often fail to capture particles below 75 microns, the multi gravity separator (MGS) has emerged as the premier solution for high-efficiency concentration. This technology combines centrifugal force with the shaking motion of a conventional table to enhance the gravitational field by many magnitudes, allowing for the separation of minerals with specific gravity differences as small as 1.0.
Choosing the right multi gravity separator manufacturers is essential for optimizing grade and recovery rates, especially when dealing with low-grade tailings or complex ores like tungsten, tin, and gold. As of 2026, the market has seen significant advancements in automation, energy efficiency, and modular chassis designs. This guide explores the four leading manufacturers setting the standard for performance and reliability in the global mineral processing industry.

How to Choose a Multi Gravity Separator Manufacturer
Selecting from various multi gravity separator manufacturers requires a deep understanding of your material characteristics and production goals. In 2026, technical support and spare part availability have become just as important as the initial machine price.
1. Evaluate Material Compatibility
Ensure the manufacturer has experience with your specific ore. While MGS technology is versatile, certain designs are better suited for precious metals (high density) while others excel at upgrading industrial minerals with lower SG differences. Always request a sample test run to verify grade and recovery targets.
2. Assess Structural Integrity and Maintenance
Continuous vibration is inherent to the MGS process. Look for manufacturers like ORO Mineral or Gravity Mining who use galvanized steel frames and robust safety guarding. A simplified chassis design reduces the time needed for occasional maintenance and ensures the machine can withstand 24/7 industrial operation.
3. Connectivity and Control Systems
Modern mineral processing plants utilize SCADA systems for remote monitoring. Choose a manufacturer that offers Ethernet/IP addressable inverters and PLC integration. This allows for real-time adjustments to rotational speed and shake frequency, optimizing the separation process even as feed density fluctuates.
4. Environmental and Operational Footprint
Multi gravity separators are prized for their low energy consumption and chemical-free operation. Compare the energy-per-tonne ratio of different models. Additionally, consider the footprint; modular and mobile-deployable designs are superior for operations with space constraints or those requiring frequent site relocation.
Frequently Asked Questions (FAQs)
What is the main advantage of an MGS over a shaking table?
The MGS uses centrifugal force to create an “enhanced gravity” field. This allows it to separate particles as small as 5 microns, whereas conventional shaking tables typically lose efficiency below 75 microns.
Can an MGS handle fluctuations in feed grade?
Yes. Top-tier multi gravity separator manufacturers design their machines to be self-regulating. By adjusting the wash water levels and rotational speed, the MGS can cope with significant changes in material grade without suffering substantial recovery losses.
What is the typical lifespan of a multi gravity separator?
With proper maintenance of the scraper blades and bearings, an MGS can operate for 15-20 years. Modern designs use wear-resistant materials like high-grade aluminum for drums and galvanized steel for frames to ensure longevity.
Does the MGS require chemicals?
No. One of the primary benefits of MGS technology is that it is a purely physical separation process. It requires no chemical or physical reagents, making it an eco-friendly choice for sustainable mining.
