Who It Is For
This solution fits projects with annual capacity from ten thousand to three hundred thousand tons Supports greenfield and retrofit Compatible with sea salt lake salt and rock salt feed
Core Process Flow
The goal is stable quality low energy use and easy maintenance The line adopts purification and softening multi effect or mechanical vapor recompression evaporation and crystallization centrifugation salt washing drying screening iodization and packaging
- Raw salt receiving and dissolving Produce brine with constant concentration Tanks with online density and turbidity monitoring
- Purification and softening Remove calcium magnesium sulfate and heavy metals by clarification filtration softening and desulfuration
- Evaporation and crystallization Use three to five effect or MVR to cut steam load Control seeding and supersaturation
- Centrifugation Use pusher or scraper centrifuge Improve cake solids and recover mother liquor
- Salt washing Wash with hot saturated brine Reduce entrained impurities and soluble calcium magnesium
- Drying Use fluidized bed hot air drying with heat recovery Control moisture and whiteness
- Screening Grade into different sizes Ensure dissolution and flow performance
- Functional addition Dose iodine and anti caking agent with uniform mixing Inline inspection included
- Packing and palletizing Bag or case packing options Metal detection weight check and trace code
