Gypsum Powder Production Line

Gypsum is an aqueous calcium sulphate. The pure gypsum is colourless and transparent. In the case where there any admixtures in it, it can be of grey, yellowish, pink, brown, or other colors.
First, gypsum rocks are fed into the production line as lumps with a size from 300 to 500 mm on average. It is necessary to crush them preliminarily, so that they are from 30 to 50 mm in size, depending on the grinding units applied downstream.
