- Gypsum also known as calcium sulfate hydrate is a naturally occurring mineral found in layers of sedimentary rock all over the world. It is formed by the evaporation and replenishment of waters containing calcium and sulfates.
- White or gray in color. gypsum can be ground into a fine powder and boiled until the majority of its moisture is removed — a process known as calcination. Adding the water back to this powder creates a pliable substance that can be formed into a shape or mold and will harden to hold that form or the substance can be added to other materials to bind them together.
- Because of its binding abilities ; gypsum is a primary ingredient in some toothpastes. It is also used as plaster to create surgical casts; as an additive in many foods; like canned vegetables; ice cream and tofu; and as an amendment; conditioner and fertilizer for agricultural applications.
Gypsum in its natural state is an ore often found layered with limestone. It is liberated from its natural state most commonly by surface mining. To get the gypsum ore into a state where it can be sold for its many uses, it is crushed to size using DDC-Sizers, Feeder-Breakers, Hammermill Crushers, Jaw Crushers or Roll Crushers and stockpiled to await further processing.
