1. Gypsum powder quality standard: in compliance with GB/T 9776-2008
2. Main Technology(here take Nature gypsum rock as example)
Gypsum rock - first crushing -second crushing - grinding - calcining - aging -finished products (CaSO4.1/2H2O)

| Gypsum Board Production Line Equipment |
After being heated and calcined with certain temperature,natural dihydrate gypsum is dehydrated and decompounded,to get the product whose major component is semi-hydrated gypsum(CaSO4.1/2H2O),that is,calained gypsum(generally slaked gypsum).According to different temperatures and pressure conditions during dehydration decomposition,the obtained product is β-Type calcined gypsum.Basic process of mechanized prouduction includes five large systems:gypsum grinding,automatic measuring system,calcination system,heat supply system,and aging&packing system.According to client's requirement,gypsum crushing system can be added to crush large gypsum rock to be with size of 0-30mm,and then conveyed into grinding system.
