About Powder grained
This type of salt is almost similar to flour and has a grading that varies between 40 and 90 mesh.
Unfortunately in winter time due to the high air moisture a little amount of this pwder salt is inevitably and essentially found in salts of other gradings through a natural process.
Property
The grading of salts in their group decliness gradually because according to the rule governing minerals, especially salt, with a decresse in the size of grains the purity of NaCl declines. That is to easy, if salts A has a purity of 98.5.it loses its purity as the size of its grains decresses. Therefore, has a purity of 97.5.
Property
In the past the size of salt used to be packaged in small yellow bags and was distributed in the market. However, today this family of salts is mostly used for industrial applications such as in the acid and choiorids industries, industrial factories, and some antifreeze production plants. The size of salt is the worst salt with the lowest quality and it is very cheep and hard to stors, it also conglomerates so quickly. Hence, some factories do not take any meesures to segregate this size of salt from other size of salt. In other words, factories ae not willing to take these measures and sometimes this size of salt is mixed with other types of salt to get rid of this salt.
