How is Gypsum Powder Manufactured?

Gypsum powder is usually produced by mining gypsum rock, followed by crushing and grinding it into a fine powder using specialized equipment. This powder is then subjected to a series of chemical and physical processes to create various grades of gypsum powder with different particle sizes, densities, and properties.

Some of the primary steps in producing gypsum powder include:

1. Crushing and grinding of raw gypsum rock to a fine powder. 2. Removal of moisture from the gypsum powder through heating. 3. Reduction of the powder size through pulverization. 4. Heating the gypsum powder to form calcium sulfate hemihydrate. This final product is then packaged and distributed for use in the construction industry.

The shelf life of gypsum powder depends on various factors, including storage conditions, packaging, and the presence of moisture or contaminants. In general, gypsum powder has a relatively long shelf life, with most suppliers guaranteeing a minimum of 12 months from the date of manufacture. However, it’s crucial to store gypsum powder properly to maintain its quality and prolong its shelf life.
