PROSALT Salt Washing Plant is a comprehensive solution for raw salt processing facilities, ensuring the highest purity with its durable construction.
The plant is optimized for the removal of impurities and purification of salt. Providing high efficiency and reliability, this unit offers the perfect solution to your industrial needs for the salt washing process.
Raw salt handling and controlled feeding start the continuous line.
Washing and mechanical separation help remove impurities from the raw material.
Dewatered salt is transferred for drying and further processing.
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.

INSIDE THE PROCESS

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:
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.

PROSALT Screw Conveyor, which is completely made of stainless steel, performs the salt conveying process in a closed circuit.
Stainless steel enclosed conveying protects salt from external contaminants. The closed system limits the release of salt and brine into the workplace while maintaining a continuous transfer.
Equipment details ↗
PROSALT Elevator is a specially designed system for the reliable and efficient vertical conveying of salt. This system is made of stainless steel and has a specially developed bearing and housing for long life and durability.
A stainless steel vertical conveyor with a specially developed bearing arrangement. It supports reliable flow, durable operation and practical maintenance while reducing the risk of sticking.

PROSALT Washing Screw Conveyor to clean dust and similar impurities from the raw salt. Through the washing process carried out by high pressure water spraying method.
High-pressure water spraying washes dust and similar impurities from raw salt. Its durable construction supports continuous washing and straightforward maintenance.
Equipment details ↗
PROSALT Mixer Cyclone is specifically designed to remove the remaining impurities by homogeneously mixing with a rotating mechanism. This system allows you to achieve high product quality in salt processing.
A rotating mechanism mixes the salt and liquid homogeneously to support the removal of remaining impurities.
Equipment details ↗
PROSALT Hydro Cyclone is designed to improve the quality and purity of the final product by acting as a density-based separator.
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.
Equipment details ↗
As the final stage of the washing plant, the PROSALT Big Cyclone plays a critical role in achieving the highest salt purity. This powerful separator efficiently separates larger salt particles from the salt solution, improving the quality of the final product.
Separates larger salt particles from the salt solution in the final part of the washing system, improving the consistency of the recovered product.
Equipment details ↗
PROSALT Dewatering Sieve is a special screen for separating washed salt from water in salt processing systems. This innovative solution recovers most of the salt particles that would otherwise be lost with water, significantly increasing production efficiency and profitability.
Separates washed salt from water and recovers particles that could otherwise leave with the water stream, limiting salt loss and improving recovery.
Equipment details ↗
PROSALT Centrifuge is a custom-engineered machine to prepare washed and cleaned salt ready for processing. This innovative product, with its specially designed baskets and high-speed rotating mechanism, reduces the moisture content of the salt down to 2%-2.4%, making it ideal for drying.
Special baskets and high-speed rotation separate moisture evenly. The source describes a 2–2.4% moisture example before drying; the achievable value depends on feedstock and operating conditions. Mechanical dewatering helps reduce clumping and prepare a consistent feed for the dryer.
Equipment details ↗
Salt Washing Plant’s platform is an innovative solution for organized and durable washing operations. With its modular and removable system, it can be easily transported and installed wherever you need it. This adds flexibility and efficiency to your processing line.
A robust modular platform organizes the washing line. Its removable design allows transport, disassembly and reassembly; the source design requires no welding during platform installation.
