The Processes of Mechanical Salt Refinery

Simple operation, stable running, much more investmetn and energy saving, and different combinations of equipment and technological adjustments can produce salt in different sizes, purities and applications.

Salt washing, crushing and impurity extraction are defined as mechanical salt refinery. The main idea is to crush large salt particles to expose impurities as much as possible and wash out impurities from the particle surface. Therefore, the salt produced also called the crushed and washed salt.

Combined the technologies of screw washing, stirred washing, countercurrent washing and roller crushing, impurities could be washed out effectively while reducing salt powder and salt loss.

After crushing and washing, the drying system drys salt to the desired moisture content, and the sieving system classifies particles of different sizes for different applications (cooking salt, table salt, industrial salt, etc.).

The final product salt is dry, white, shiny, and free-flowing.

• Based on the basic data and varying requirements of different plants, the process needs to be professionally customized and appropriately adjusted.
