Natural Gas, Oil or Coal
Features of the gypsum powder production line
The calcination system is the key procedure of the production line. The vertical calcinor is used in the calcination system. The main body of the calcinor is composed of delicate and intensive radiation pipes, in which hot air goes. Hot air is made inside the furnace by burning oil, natural gas, LPG or coal, and it circulates between the hot air furnace and the calcinor. At the bottom of the calcinor is mounted a Roots blower, which blows the gypsum upwards through the space between the hot air pipes. The gypsum powder inside the calcinor is in a boiling state, so the calcinor is also called boiling furnace. Being heated, the gypsum powder becomes lighter and it goes out of the calcinor automatically.
The advantages of this calcining system:
Simple structure, free of maintenance
Compact machine, occupy less space
Gypsum with this system has better physical characteristics and the setting time is easy to control
Better dust collecting
