Calcination Unit
Calcination is an important part of gypsum processing, quality of calcination directly determines quality of the final product.
Gypsum powder enters the fluidized gypsum boiling furnace for calcination after being pre-dried.
Discharge temperature of calcination process is 150-160 °C, by adjusting boiling furnace internal temperature, etc.,
parameters of the finished building gypsum can be adjusted to meet different requirements.
New-Type Boiling Furnace Calcination
Features of Calcination System:- Low-temperature heat source is applied, to prevent gypsum from getting over heated, by controlling discharge temperature, except a small amount of dihydrate and anhydrite gypsum, the major containment of the finished product is hemihydrate gypsum, which is an ideal condition with stable physical performance.
- Simple structure, uneasy to damage; vertical design with compact size, room-saving.
- High qualified products.
- Energy saving, over 95% high thermal efficiency, very low energy loss.
- Eco-friendly, both built-in dust collector and bag type dust collector are applied.
Heat Source:
Coal and gas (light oil) burns serve as heat source, hot air as heat exchange medium, thermal efficient > 85%; preheating utilization system is applied, leading exhaust gas to the outlet position, getting it mixed with the high temperature flue gas stroke, to effectively save energy.
