Augers and Conveyors
Screws for washing and conveying salt, and belt conveyors that move salt between the stages of a production line.
Salt production lines
Salt Washing Lines
Washing raw salt and separating the brine before drying.
Overview
Washing removes dirt, suspended impurities and part of the soluble impurities from the surface of the salt crystals. It is usually done with saturated brine rather than fresh water, so that the salt itself does not dissolve during washing.
After washing, the brine is separated from the salt in stages such as hydrocyclones and centrifuges, and the washed salt moves on to drying. The brine can be settled and recirculated within the line.
Equipment related to this line
Tanks and Hydrocyclones
Equipment for holding, mixing and thickening salt slurry and brine in the washing stage.
Centrifuges
Machines that separate brine from salt crystals by centrifugal force before drying.
General planning considerations
- The type and proportion of impurities in the raw salt.
- How the washing brine is prepared and recirculated.
- The moisture level acceptable before the salt enters the dryer.
Related stages
Salt Drying Lines
Salt drying lines: rotary and surface dryers with their heaters and blowers, reducing the moisture of salt after washing.
Salt Refining Lines
Salt refining lines: general stages that raise salt purity — washing, separation, treatment and drying — defined by the raw salt and the target specification.

Frequently asked questions
Why is salt washed with brine instead of water?
Fresh water dissolves part of the salt itself. Saturated brine removes impurities from the crystal surface while limiting salt losses.
Can a washing stage be added to an existing line?
Often it can, depending on the available space and the layout of the current line. See production-line modernization or send us details of your line.
