Audited Supplier Red mud dryer is also known as the three layers of drum dryer, three return cylinder dryer, based on the single-cylinder dryer, developed and manufactured, which is an industrial dryer on non-viscous, liquid material. At present three-cylinder dryer made by Dingli company, with mature technology, through the drying of sand, fly ash, coal, mineral materials, slag, and other material, the effect is very good.
1. The red mud dryer is made of alloy steel plate manufacturing, the wear-resisting 3-4 times of ordinary steel, the service life of the equipment is more than 10 years.
2. Material initial moisture content 15%, final moisture to ensure below 0.5-1%, which is the preferred product of the cement plant, GGBS, and dry mortar production line.
3. The sand dryer's thermal efficiency is as high as 80%, at the same time, the total power is low, with 40% energy saving.
4. The fuel can be adapted to coal, oil, and gas, it can be dried under 20-40mm particles material, aggregate, powder material.
5. The red mud covers an area of about 40% lower than a single drum dryer and civil investment is reduced by about 50%.
6. No air leakage phenomenon solved the sealing difficulties, modular units, installation is convenient.
7. The discharge temperature is < 50 ºC, which can be directly fed to libraries, without cooling.
8. The system uses PLC technology to achieve centralized automatic control, convenient operation, and reliable performance.
After the red mud enters the drying drum, it is divided into the following working areas: One is the guide area. The red mud enters this area and quickly evaporates water in contact with the high-temperature hot air. The red mud does not form a bond under the movement of the guide plate with a large lead angle. Then it is led to the next lower production area: the second is the pick-up cleaning area, where the wet material is picked up by the pick-up board to form a material curtain. When the red mud falls, it is easy to form a sticking drum wall phenomenon. In this area, due to the equipment design The cleaning device, the cleaning device cleans the red mud adhered to the inner wall very reasonably. In this process, the cleaning device also breaks the agglomeration of the red mud balls, thereby increasing the heat exchange area and increasing the drying rate: It is an inclined lifting plate area, where the wet red mud is already in a low-moisture and loses state, and the red mud has no adhesion phenomenon in this area. After sufficient heat exchange, the red mud reaches the required moisture state and enters the discharge area: The fourth is the discharging area. The drum is not equipped with a copy board in this area. The red mud rolls and slides to the discharge port in this area to complete the entire drying process.
Dryers are widely used in building materials, metallurgy, mineral processing, chemical, cement, and other industries. They can be used to dry slag, calcium carbide slag, limestone, clay, river sand, quartz sand, water slag, and other materials.
