Device for controlling cohesive force of beta gypsum prepared from ardealite

A bonding force control device for beta gypsum prepared from ardealite comprises a hydration pool, a mixed jet flow connector and a stirring device, a jet flow pipe of the mixed jet flow connector penetrates through the hydration pool to be communicated with the hydration pool, a fixing plate of the stirring device is located on the upper side face of the hydration pool and connected with the hydration pool, and stirring blades are located in the hydration pool. Phosphogypsum powder and a cementing agent are carried by high-pressure airflow to enter the mixing cavity from the drainage pipe and the glue guide pipe to be mixed and then enter the hydration pool from the discharge port of the spray pipe to impact dihydrate gypsum slurry particles and mother liquor, and the slurry gradually loses plasticity in the hydration and evaporation processes. The device overcomes the problems that in the original beta semi-hydrated gypsum hydration process, the bonding force with crystals is poor when phosphogypsum is adde
