The drying process use two rotating cylinders to reduce the kaolinitic clay moisture from 30% to a requirement of the product below 1%. Initially to achieve this was necessary twice passing clay through the dryer, thus were modified operating conditions as drum speed, feed rate, drying air velocity, in order to achieve the necessary features in one product step without affecting the ceramic properties of it, which were determined by TGA, XRF and reactivity of alumina kaolin. On the other hand energy efficiency improved by optimizing combustion, reducing cold air infiltration 1000% to 200%, the specific fuel consumption was reduced from 4.48 to 2.98 kWh / kg of water evaporated, tripling the production without affecting the physical and mineralogical characteristics of the clay.
