Professional Production Line for Sea Salt Washing and Refinement

Designed for processing lake and sea salt, this complete production line covers crushing, multi-stage washing, pusher centrifuge dewatering, and drying. Suitable for both edible and industrial salt production.

The integrated system includes raw salt pre-crushing, screw and agitated washing with counter-current stages, continuous pusher-centrifuge dewatering, and hot-air or fluidized-bed drying. Downstream modules feature in-line screening and packing capabilities, designed for stable purity, low moisture content, and energy efficiency.

• Raw materials: lake salt, sea salt
• Control system: PLC with inverter-ready drives
• Contact materials: stainless steel options available based on hygiene requirements

Drying module after centrifuge dewatering

1. Pre-crushing: Reduces bulk salt to the optimal size range for effective washing and classification.
2. Multi-stage Washing: Combines screw and agitated washing with counter-current rinsing to remove both insoluble and soluble impurities, improving product purity.
3. Continuous Dewatering: Two-stage pusher centrifuge significantly reduces cake moisture before drying, enhancing energy efficiency.
4. Drying & Screening: Hot-air or fluidized-bed drying achieves target moisture levels, followed by precision screening and packing.
