The waste produced in the alumina production process is reddish-brown because it contains a large amount of hematite, so it is called red mud. Different from ordinary sludge, red mud not only has high water content and high viscosity, but also contains a large amount of alkali and impurities such as fluorine and aluminum.

  In view of the characteristics of high humidity and high viscosity of red mud, Zhengzhou Jiutian has developed a complete set of red mud dryer production line to help the treatment and recycling of red mud. The internal structure of the equipment has been upgraded, and the drying process of co-current, counter-current and mixed-flow is adopted, and the "rotary harrow crushing" device and the "material guiding and lifting" system are specially designed. At the moment of entering the red mud dryer, the broken red mud quickly exchanges heat with the high-temperature hot air, evaporating a large amount of water. In the high-speed drum, the red mud is continuously scattered, thrown up, and ejected, and a hard shell is formed on its surface. Before entering the next drying stage, the red mud has become non-sticky and non-sticky, which greatly reduces the phenomenon of red mud sticking to the dead corners of the cylinder and accumulating and blocking materials, so that it can be dried quickly.

  Zhengzhou Jiutian is a professional manufacturer of red mud dryers, if you are interested in red mud dryer and want to know more information, please feel free to contact us.
