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.
As a byproduct of the beer brewing process, beer yeast has high nutritional value, but its high moisture content limits its storage and reuse. Yeast drying technology is becoming increasingly important in the beer industry and has become a key link in res
Paper pulp dryers are widely used in the papermaking industry and waste paper recycling industry, playing a key role in saving resources, reducing environmental pollution and improving the efficiency of the papermaking industry.
Brewer's grains are the main by-product of the beer brewing process. They have the characteristics of high moisture content and high viscosity. If they are not handled properly, they are likely to cause environmental pollution. A dedicated brewer's grai
Coffee grounds are a byproduct of the coffee making process and are usually considered waste, but they actually have multiple recycling values. Coffee grounds have a high water content and are easily spoiled, making them difficult to store and transport,
