Gypsum production process

Art work flow
The production process of Î²-type plaster is generally: ore storage â†’ crushing â†’ homogenization â†’ calcination dehydration â†’ aging â†’ grinding and mixing â†’ packaging, first calcined with a wok and then calcined.
The raw gypsum dry calcination process is as follows: raw gypsum is transported and selected from the quarry to ensure continuous feeding and stable quality. The feedstock is subjected to a section of crushing ( chopper crusher ) to below 8 cm, and then to a second stage of crushing ( hammer crusher ) to less than 2 cm, and then calcined into a calcining kiln through a bucket elevator. By controlling the temperature of the kiln, Î²-type hemihydrate gypsum, anhydrite gypsum and burnt gypsum can be separately produced.
The Î±-type wet calcination process and process are generally: gypsum raw material warehouse â†’ sieving machine â†’ autoclave autoclaving and drying â†’ broken pulverization â†’ homogenization storage â†’ Î± and Î² gypsum mixing â†’ packaging and handling. The process for producing Î±-type hemihydrate gypsum by hydrothermal method is:
Gypsum ore â†’ crushing â†’ milling â†’ reaction kettle (adding water and chemicals) â†’ cleaning â†’ dehydration drying â†’ packaging.
