Production stages of various types of constructional powder plaster are divided into ten stages in general, and different special
machines are used to perform each of these stages. These ten steps are: blasting gypsum, carrying, crushing, sieving, baking,
dusting, milling, storing, packing and finally loading. First, gypsum is transported from the mine to the factory depot, and after
the production process, the product is packed in bags of different weights and transported to the target market by trucks. It
should be noted that different types of gypsum with different quality and characteristics are offered in distinct packages and
prices.
