Gypsum or Calcium sulfate dihydrate (CaSo 4 .2H 2 O) is a mineral of calcium that is mined in various parts of the world. It is also formed as a by-product of flue gas desulphurization in some coal-fired electric power plants. There are different kinds of Gypsum and are listed below. Alabaster – pure white, fine-grained and translucent gypsum.

A different philosophy applies to the crushing and grinding of Gypsum. Gypsum as a mineral (CaSO4·2H2O) is number 2 on the Mohs scale of hardness; only Talc is softer. This would lead one to believe that it should be easy, to crush, like coal for example, and our equipment was formerly designed on this basis.
