How does the Salt Washing Processing Line work?
The Salt Washing Processing Line adopts an automated workflow to transform raw salt into high-purity finished salt through crushing, washing, dewatering, drying, and packaging. The main process includes:
- Raw Salt Feeding – Raw salt is stored in a large-capacity silo and fed evenly into the production line through a vibrating feeder.
- Crushing – Large salt blocks are crushed into uniform particles, ensuring efficient washing and stable downstream processing.
- Salt Washing – A combination of spiral washing and mixing washing removes mud, sand, and other impurities through a multi-stage cleaning process.
- Screening – A multi-layer vibrating screen separates salt into different particle sizes while automatically removing impurities and oversized materials.
- Dewatering – A high-speed centrifuge efficiently removes excess moisture, preparing the salt for the drying process.
- Drying – A fluidized bed dryer with a hot air circulation system dries the salt evenly while reducing energy consumption.
- Iodization (Optional) – An automatic dosing system accurately adds iodine to produce qualified iodized salt according to customer requirements.
- Automatic Packaging – The finished salt is accurately weighed and packed into bags or ton bags for convenient storage and transportation.
- Intelligent Control – A PLC control system with a touchscreen monitors and manages the entire production process, ensuring stable operation and high production efficiency.
This fully automated process delivers high-purity salt, low labor costs, stable product quality, and continuous production, making it ideal for sea salt, lake salt, and industrial salt processing plants.
Salt Washing Machine Production Line Layout
Based on the provided layout diagrams, the production line adopts modular design with equipment connected by conveyors to ensure smooth material flow.
Typical layout includes: Raw Material Silo → Crusher → Spiral Salt Washing Machine → Mixing Salt Washing Machine → Screening Machine → Centrifuge → Fluidized Bed Dryer → Iodizer → Ton Bagging Machine.
Detailed Introduction of Core Equipment
Spiral Salt Washing Machine
- Material: 304/316L Stainless Steel.
- Rotation Speed: 0-60 rpm (variable frequency adjustable).
- U-shaped trough design to prevent material overflow.
- Double spiral structure for enhanced washing and conveying effect.
- Spiral blades made of wear-resistant material for extended service life.
- Drainage port at the bottom for easy cleaning and slag discharge.
- Sealed bearing design at both ends to prevent salt leakage.
Raw salt enters the U-shaped trough from the feed inlet and is conveyed forward by the spiral blades. Washing water is injected into the trough simultaneously, allowing full mixing of salt and water. Through the agitation and conveying action of the spiral, impurities in the salt dissolve in water and are discharged through the drainage port, achieving the washing purpose.
Mixing Salt Washing Machine
- Material: 304/316L Stainless Steel.
- Mixing Speed: 0-120 rpm (variable frequency adjustable).
- Cylindrical tank design with large internal space.
- Multi-layer mixing blades for thorough mixing.
- Automatic water replenishment system to maintain stable washing liquid concentration.
- Conical bottom design for easy discharging and slag removal.
- Equipped with observation window and cleaning port for convenient maintenance.
Preliminarily washed salt from the spiral salt washing machine enters the mixing salt washing machine. Under the powerful mixing of the blades, salt and washing water are fully mixed, and fine and soluble impurities are further removed. The washed salt exits through the discharge port to the next process.
Screening Machine
- Material: 304/316L Stainless Steel.
- Screen Layers: 2-5 layers.
- Screen Mesh Size: Configurable as needed (e.g., 20 mesh, 40 mesh, 60 mesh).
- Vibration Frequency: Adjustable.
- Multi-layer screen design for multi-stage classification.
- Vibration motor drive for high screening efficiency.
- Stainless steel screen with corrosion resistance and uniform aperture.
- Equipped with dust collection device to reduce dust pollution.
- Quick screen replacement for different product requirements.
Washed salt enters the screening machine through the feed inlet. Under the vibration of the motor, the screens vibrate, and salt particles pass through different screen layers according to size, achieving classification. Salt of different particle sizes exits through respective discharge ports.
Crusher
- Material: 304/316L Stainless Steel.
- Crushing Particle Size: 0.1-5mm (adjustable).
- Rotation Speed: 3000-6000 rpm.
- High-efficiency crushing chamber for high crushing efficiency.
- Blades made of wear-resistant material for extended service life.
- Overload protection device for equipment safety.
- Easy disassembly and cleaning for food hygiene compliance.
- Equipped with noise reduction device.
Large raw salt blocks enter the crushing chamber through the feed inlet and are cut and crushed into fine particles by the high-speed rotating blades. The crushed salt exits through the discharge port to the next process.
Centrifuge
- Material: 304/316L Stainless Steel.
- Rotation Speed: 0-3000 rpm (variable frequency adjustable).

- Horizontal spiral discharge structure for continuous discharge.
- Variable frequency control for adjustable speed to suit different materials.
- Full stainless steel construction for corrosion resistance and food hygiene compliance.
- High automation with minimal manual intervention.
- Stable operation with low noise.
Salt slurry enters the centrifuge and, under centrifugal force from high-speed rotation, salt particles are thrown to the drum wall while water exits through holes in the drum. Dewatered salt is discharged through the spiral conveyor.
Fluidized Bed Dryer
