Clay is widely used, mainly used in papermaking, ceramics and refractory materials. Secondly, it is used in coatings, rubber fillers, enamel glazes and white cement raw materials. It is also used in small quantities in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, Pesticides, medicines, textiles, petroleum, chemicals, building materials, national defense and other industrial sectors.

The clay dryer can handle various materials, such as mixed mortar, sand, cement slag, clay, kaolin, Bentonite，gangue, mixture, fly ash, gypsum, iron powder and other raw materials.

• The wet material into the inner cylinder of the feeding end, is quickly pushed to the spiral lifting plate by the spiral guide plate. With the rotation of the cylinder, the spiral lifting plates set up in three cylinders make the materials lifted, at the same time, the materials continue to roll, scatter and do longitudinal motion. At the same time the hot gas flow from the heat source successively enters the inner drum, the middle drum and the outer drum and to meet the material for a strong heat exchange.
• The thermal conductivity of metal plate is faster than that of materials, steel plate and lifting plate of cylinder of the first heat, then the heat by conduction and radiation transmitted to the material, the material is heated, when the temperature rises to the evaporation temperature, water vapor is separated from the material, discharged with the dust into the atmosphere, so as to achieve the purpose of drying materials.
