Industrial Salt Washing Plant
A sequential salt washing plant that receives raw industrial salt, washes it to remove clay and sediments, classifies it by grain size, and prepares it for industrial use or packaging.
Project Concept
An industrial salt washing factory operating via a sequential system: receiving raw salt, washing with water to remove clay and sediments, classifying by grain size, and storing ready for packaging or industrial use.
Project Overview
Washing and classifying raw salt converts a natural raw resource into a market-ready industrial product. The sequential system ensures continuous production with minimal waste, serving water treatment, food, and chemical industries.
Main Components
Key equipment and units that make up the production line
Feeder Unit
- Receives raw salt from trucks or silos
- Continuous feed to first conveyor
- Equipped with flow control gates
- Reception capacity: 1–100 tons/day
Conveyor 1 – Transport to Washing Unit
- Corrosion-resistant or anti-abrasion steel belt
- Adjustable speed
- Length: 5–15 m (depending on plant design)
Washing Unit
- Washing tank or rotating drum
- Running water with optional water recycling
- Removes clay and impurities
- Continuous agitation with mixer or hydraulic pumps
- Water temperature control: 25–40 °C
Conveyor 2 – Transport to Screening Unit
- Water and moisture resistant belt
- Directly transports washed salt to screening
Screening Unit – Classification
- Multi-size vibrating screen
- Separates large and undersized grains
- Sorting accuracy: 0.5–10 mm
- Removes remaining stones and debris
Conveyor 3 – Transport to Storage
- Moisture-resistant belt
- Directly transports pure salt to silos or stacking area
Storage / Stacking Unit
- Temporary silos or open-air storage
- Salt level monitoring
- Capacity: 5–100 tons per project scale
Operating Cycle
Cycle duration: Batch: 4–8 hours per ton; Continuous: runs to 100 tons/day
