Gypsum is a mineral found in many items we use every day, like toothpaste and shampoo. It is also used to make Portland cement and drywall, create molds for dinnerware and dental impressions, and to build roads and highways. Other uses of gypsum include: For settling particles in ponds For brewing beer and making mead For creating drywall, wallboard or plasterboard For binding tennis court clay As molds for dinnerware, car windows and dental impression plasters As a hardening element in Portland cement In roads and highways As sidewalk or classroom chalk In hair products, like shampoo, and creams And much, much more.
It was the star of many early movies Before the era of computer generated imagery, early Hollywood filmmakers used a number of substances to create fake snow on set , including cotton, cornflakes and soap flakes.

In recent years, the gypsum industry has developed rapidly. Gypsum building materials are increasingly welcomed by the market and recognized by society with their applications becoming more and more widespread.
According to the US mining forecast, the world's gypsum demand will increase at a rate of 2. It is estimated that the world's gypsum demand will reach million tons in The total annual consumption of the gypsum board will reach 2.
With the increase in the market demand for gypsum powder, the requirements for its production technology are getting higher and higher, so the price has risen accordingly.
The price of gypsum powder is generally calculated in tons. Its price varies with its accuracy and use. Total cost of gypsum supply and application per ton of pure CaSO 4. Some countries have the highest reserves in the world, for example, there are 1. The largest consumption area of gypsum is the building decoration material industry, which is mainly used to manufacture gypsum boards for construction and decoration.
The building gypsum powder production line is usually divided into gypsum mining process, crushing, grinding and calcination processes according to technical requirements. The mining technology of gypsum ore is divided into two categories: the mining of fibrous gypsum ore and the mining of alabaster, ordinary gypsum and anhydrite mines. Due to the difference in physical and mechanical properties of the ore and surrounding rock, the mining technology of these two kinds of gypsum mines is very different.
Fibrous gypsum has low hardness and its rock consolidating coefficient is 1. Because it is brittle, it will easily become fine ore to be lost.
Due to the high price of the ore, most fibrous gypsum mines adopt the longwall method, selective mining and filling method. The mining techniques of alabaster mine, ordinary gypsum mine and anhydrite mine are similar.
The room and pillar mining method generally m in width and breasting method are adopted. The drilling of gypsum ore is easy, but the explosive consumption is large, generally 0. The roller drilling rig is modern new drilling equipment. It is suitable for drilling operations of various hardness of minerals and rocks with the characteristics of high perforation efficiency, low operating cost, high mechanization and automation.
At present, it has become a widely used perforation equipment in open-pit mines all over the world. Gypsum Powder manufacturers cater to such needs.
Drywall is created out of gypsum powder. This powder is led towards evaporation of most of its content of water and carbon dioxide to be converted to Calcium Sulfate Hemihydrate also known as Plaster of Paris.
Plaster of Paris converts back to CalciumSulfateDihydrate when it is mixed back with water. Such slurry is transferred to space between two hard sheets of heavy paper.
It is flattened and allowed to set for forming drywall. The resulting drywall is subject to further drying, cutting, finishing and packaging for sale. Dry walls made of gypsum powder are thermal resistant and fire resistant, provides sound insulation, is durable and easy to repair.
