Introduction of gypsum

Gypsum is a monoclinic mineral and is a hydrate whose main chemical component is calcium sulfate (CaSO4). Gypsum is a versatile industrial and building material. Can be used in cement retarder, gypsum construction products, model making, medical food additives, sulfuric acid production, paper fillers, paint fillers, etc.

The micro porous structure and heat dehydration of gypsum and its products make it excellent in sound insulation, heat insulation and fire resistance.

Resource distribution

The world's largest producer of gypsum is the United States. In the United States, gypsum deposits are distributed in 22 states and there are 69 mines, the largest being fort dodge, Iowa. Next is Canada; France takes a leading position in European gypsum production; Again for Germany, England, Spain. China is rich in gypsum mines. National 23 provinces (area) have gypsum mine output.

Gypsum Processing Plant

1. The large size crusher gypsum ore is broken into less than 30mm granule by crushers. Then be delivered to the grinding mill;
2.Gypsum powder production line adopts Chinese domestic mature and advanced process and equipments, such as vertical mill and boiling furnace etc;
3.The qualified gypsum powder, which reaches required fineness, could pass separator and is transported into boiling furnace by air to be calcined. The rest big powder would return mill again. Boiling furnace is the most widely used equipment in china in building gypsum process industry. The virtue is its simple structure and easy operation;
4.Calcined gypsum powder would be stored by silo or packed by bags for sale, or transported into following workshop directly;

Application Of Gypsum

1. Medical application
Gypsum has certain antipyretic effect on febrile animals and can be used in the treatment of febrile diseases.
2. Direct application of raw ore
Mainly used for cement retarder, ceramic mold. Food industry, such as coagulant
3. Applications in building materials
Mainly is the two water gypsum ore after processing intoα- half water gypsum orβ- half water gypsum, made of all kinds of gypsum products, used in building materials.
4. Special industries gypsum products
Mainly for gypsum ore has a higher purity requirements, the use of relatively small industrial filler industry.
