Gravity Separation Machine for Efficient Recycling
Yung Hsing Machinery provides advanced gravity separation equipment engineered for precise, density-based sorting in recycling and industrial applications. By leveraging natural differences in material density, our systems deliver high-purity outputs with low operating costs for plastics, e-waste, and non-ferrous metals.
What is Gravity Separation?
Gravity separation is a physical process that sorts materials by their density. Instead of chemicals or high thermal energy, it uses air flow, vibration, or a fluid medium to separate light and heavy fractions efficiently and sustainably.
Common gravity separation techniques include:
- Sink–Float Separation – Submerge materials in a controlled-density liquid to split lighter plastics from heavier metals.
- Air/Densimetric Table Separation – Use deck vibration and upward air to stratify and discharge by weight.
- Jigging & Shaking Table – Apply pulsation/oscillation to concentrate heavier fractions.
- Spiral Concentrators – Employ gravity-driven spirals where lighter particles move outward and heavier particles move inward.
How a Gravity Separator Works
| Step | Process Description | Key Function |
|---|---|---|
| 1. Feeding | Mixed materials enter via conveyor or hopper. | Ensures steady and controlled input. |
| 2. Fluidization | Air flow (or water in sink–float systems) passes through the bed. | Creates density-based stratification. |
| 3. Vibration/Inclination | The deck vibrates and tilts; particles respond by mass and shape. | Enhances layering and differential movement. |
| 4. Stratification | Material forms layers: light vs. heavy fractions. | Separates recoverable streams by density. |
| 5. Discharge | Fractions exit from dedicated outlets. | Collects clean, recyclable outputs. |
This continuous process enables high throughput and accurate recovery of valuable materials while minimizing energy and maintenance overhead.
Applications of Gravity Separation Machines
