1. A material supplement stabilizing system is deployed to achieve stable supplement of the fluidized bed combustion boiler, and to stabilize material supplement and heating. Material supplement stabilizing system consists of material supplement stabilizing bin and conveying device (metering screw or belt weigher).
2.Calcining system applies hot air boiling furnace calcining process to perform even calcination on gypsum material.
3. Cooling device added to cool down calcined gypsum before it enters silo, to prevent gypsum from deterioration caused by over temperature.
4.Silo turn-over system: materials at different time periods feature different quality, therefore products made from them feature different quality. The silo turn-over system can evenly mix new and old materials, make the products share the same quality. Besides, the system prevents overheating deterioration caused by heat generated by powder accumulation.
5. The dust removal system applies a bag type dust collector, to ensure dust generated during pre-drying, conveying, grinding,calcination and aging processes get cleaned before discharging outside, to meet working environmental requirements.
6. Distributed control system is applied, to do centralized control on distributed devices.
