01

Prepare the feed

Raw salt handling and controlled feeding start the continuous line.

02

Wash & separate

Washing and mechanical separation help remove impurities from the raw material.

03

Move to the next stage

Dewatered salt is transferred for drying and further processing.

Process technology

The PROSALT Salt Washing Plant represents the pinnacle of salt refining technology. Designed to handle the harshest raw salt conditions—whether sourced from lakes, seas, or mines—this plant utilizes a multi-stage cleaning process to elevate the quality of your raw material. By meticulously removing soluble and insoluble impurities, we ensure that the resulting salt meets international standards for both industrial and edible consumption.

Our washing technology is centered around the Counter-Current Washing Principle, which maximizes the contact between the salt crystals and the brine, ensuring that contaminants are stripped away without compromising the crystal structure.

Raw Salt Bunker

Raw salt bunker

PROSALT Silo allows the raw salt to be sieved and fed continuously to the salt washing system. It offers many important advantages in terms of uninterrupted and efficient progress of the production process:

  • Special Design Vibration Mechanism: The storage discharges smoothly and eliminates the risk of clogging.
  • Mechanical Rotator: Allows for precise adjustment of the flow rate, enabling the washing process to occur at an optimal level.
  • Non-stop Production: Continuous feeding eliminates interruptions in the salt processing line. This increases production capacity and saves time.

Screens and continuously feeds raw salt. A vibration mechanism helps discharge the bunker without clogging; a mechanical rotator adjusts the flow to keep the washing line running.

Hydrocyclone Separator

Hydrocyclone

PROSALT Hydro Cyclone is designed to improve the quality and purity of the final product by acting as a density-based separator.

  • Elimination of Heavy Impurities: When a brine mixture containing impurities such as sand, clay particles or other dense substances enters the hydrocyclone, centrifugal force expels these heavy impurities.
  • Pure Salt Provides Higher Efficiency: The salt solution, free of impurities, flows more smoothly through your facility. This saves time by reducing blockages and speeding up the processing flow.

Density-based separation uses centrifugal force to remove heavier particles such as sand and clay from the brine mixture. A cleaner stream helps reduce blockages and maintain process flow.
