plaster equipment 
When heating and calcining the dehydrate gypsum and chemical gypsum (ardealite, desulphurization plaster, fluorgypsum), the dehydrate gypsum is decomposed, we get the semi-hydrated gypsum, i.e., plaster of Paris.
Gypsum powder plant 
According to the temperature and pressure during decomposition, the products   include high intensity gypsum and plaster of Paris.The plaster breaking system, calcined system and grinding aging system are the main parts. 
plaster machinery  whole process is as following:
Gypsum mine----- homogenization ---- rough breaking --- detailed breaking----Measurement(calculating)----calcined(oil,coal,dust-collector)--homogenization(dust-collector)----grinding(dust-collector)---aging (dust-collector)----- package
