how to remove discolor salt and stones from salt?

The optical sorter has great performance in sorting sea salt and rock salt.It can remove discolor salt ,stones and other foreigh material.
Benefits of Salt Color Sorter
1,Inexpensive sorting of various kinds of salt by color and brightness is possible
Slightest color and brightness differences,for example white/light and dark grey as for anhydrite or slightly brown shades as for sulphur,are relibaly detected and are available as sorting parameters.
2,The material yield is maximised by accurate detection and exact sorting.
3,Effective corrosion protection with special powder coating as well as the use of special stainless steel ensure long-term operation with long endurance.
4,Maximizing yield
The high precision ejection system minimizes false reject of good grain, delivering a highly concentrated reject stream
Due to minimal loss of good grains on the first pass, most grain applications do not require a re-sort while still running on a high capacity, however, a re-sort option is available if required
