Gypsum ore is extracted from quarries or mines and then broken into smaller, more manageable sizes. The water content of the material is then assessed before entering the grinder. Gypsum ores with water content greater than 0.5% (by weight) are treated with rotary dryers. Once the moisture content reaches the appropriate level, the mill reduces the material to a fine chalky powder, commonly referred to as ground gypsum. The terrestrial gypsum is then calcined in a large kettle reactor to remove most of the water in the gypsum.

After the pretreatment is complete, the calcined plaster (called stucco) is rehydrated with water and other ingredients to form a slurry. This mixture is applied between layers of paper on board assembly equipment. The rehydrated plaster hardens to its original rock state and forms a lasting bond with the paper. Finally, the sheets are cut into different lengths and fed through the dryer to remove any residual moisture.

The fabric refining stage units a precedent for the high-quality of the closing product. As you simply study in the Gypsum Processing Overview, moisture ranges and drying play a key position in the manner of turning gypsum into wallboard. Since pretreatment is vital for the first-rate of subsequent methods and ultimate products, dependable and environment friendly drying tools such as rotary dryers ought to be used.
