Overview
The line integrates 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 include in-line screening and packing. The design targets stable purity, low moisture and efficient energy use.
- Raw materials lake salt, sea salt
- Control PLC with inverter-ready drives
- Contact materials stainless options by hygiene needs

Process Flow
- 1) Pre-crushing
Reduce bulk salt to the size range required for effective washing and classification.
- 2) Multi-stage Washing
Combine screw and agitated washing with counter-current rinsing to remove insoluble and soluble impurities and improve purity.
- 3) Continuous Dewatering
Two-stage pusher centrifuge lowers cake moisture before drying and improves energy performance.
- 4) Drying & Screening
Hot-air or fluidized-bed drying to target moisture followed by screening and packing.
Core Equipment Pusher Centrifuge
Horizontal two-stage pusher centrifuge for salt crystal solid–liquid separation with PLC control. Typical specs include low moisture after separation and automatic continuous discharge modes, supporting stainless contact materials according to product grade.
Recommended Configurations
| Scale | Suggested Lineup |
|---|---|
| 100–300 t/day | Two-step crushing, screw + counter-current washing, mid-size pusher centrifuge, hot-air or fluidized-bed dryer, automated packing with in-line screening |
