METHOD FOR OBTAINING STABILISED ANHYDRITE III

摘要

A process for obtaining stabilized anhydrite III comprising a drying step in a curved dryer at temperatures comprised between 100-400 °C, and a second stabilization step in a straight dryer where stabilization will be a function of the air speed within the dryer and the inlet and outlet temperatures of the product and in which there is a possibility of vaporising the product coming out of the straight dryer.
