Continuous Crystal Separation and Dewatering Salt Pushing Centrifuge System

This solution applies a two-stage pusher centrifuge for continuous salt crystal separation and dewatering. It suits sea salt, rock salt, and industrial salt. The multi-stage design enables optional in-machine washing and lowers discharge moisture to reduce downstream drying load.

1. Continuous feed: Salt slurry enters the first basket.
2. Primary dewatering: Mother liquor drains through the screen to form a cake.
3. Push to second stage: The cake advances for final dewatering.
4. Optional washing: For higher purity, wash before the second stage.
5. Continuous discharge: Low-moisture cake exits steadily.

• Continuous operation with high solids yield and low specific costs.
• Low residual moisture to reduce drying energy.
• Multi-stage designs with high availability and minimal maintenance.

• Crystal size: target ≥ 150 µm for fast drainage.
• Feed solids: typically 25–65 wt% for pusher centrifuges.
• Materials: use corrosion-resistant steels (e.g., 316/duplex) on salt-contact parts.
• Service: maintain hydraulic pusher system and motor/controls to OEM guidance.
