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)
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.
