Gypsum powder production line brief introduction:
1. Brief introduction
Natural gypsum generally includes dihydrate gypsum and anhydrous gypsum. In order to get the valuable materials, generally, we get semi-hydrated gypsum through heating the dihydrate gypsum.
CaSO4·2H2O heating CaSO4·1/2H2O+3/2 H2O↑
It is the process.
The calcined semi-hydrated gypsum can widely be used for plasterboard, decoration board, gypsum block, stucco gypsum, and molding gypsum etc.
2. Production scale
10000 tons to 300000 tons /year
3. Main technology
A: fluidized furnace technology (calcine after grinding)
Gypsum mine →first breaking →second breaking →grinding →calcining →aging →finished products (CaSO4·1/2H2O )
B: Rotary kiln technology (calcine after grinding) or (grinding after calcine)
Gypsum mine →first breaking →second breaking →calcining →grinding →aging →finished products (CaSO4·1/2H2O )
4. Raw materials
Content of CaSO4·2H2O in gypsum mine >80%.
The grade of mine and the crystal configuration will influence the quality ofsemi-hydrated gypsum.
