Product Description

Product Description

^{Red mud dryer is also known as the three layers of drum dryer, three return cylinder dryer, on the basis of the single cylinder dryer, developed and manfactured,which is an industrial dryer on non-viscous, liquid material .At present three-cylinder dryer made by Dingli company,with mature technology, throughthe drying of the sand, fly ash, coal, mineral materials, slag and other material , the effect is very good.}

<sup>Purpose of red mud drum dryer

1. Drying red mud: The main function of the red mud drum dryer is to dry the wet red mud and reduce its moisture content to a certain extent for subsequent processing and transportation.

2. Improve production efficiency: The red mud drum dryer adopts the advanced hot air circulation principle, which can quickly evaporate the water in the red mud, improve the drying efficiency, and make the red mud drying process faster and more efficient, thereby improving the overall production efficiency.

3. Reduce transportation costs: Since the moisture content of red mud is reduced after drying, its weight is also reduced accordingly, which helps to reduce the cost expenditure during transportation. At the same time, the dried red mud is easier to store and transport, reducing the loss and waste during transportation.

4. Environmental protection and energy saving: The red mud drum dryer adopts advanced combustion technology and heat recovery technology, which can effectively reduce energy consumption and emissions, help protect the environment and achieve sustainable development.

5. Resource reuse: The dried red mud can be used as building materials, roadbed materials, etc., which not only reduces dependence on natural resources, but also reduces waste disposal costs and realizes the recycling of resources.</sup>

Product Features

<sup>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 products of the cement plant, GGBS and dry mortar production line.
3. The sand dryer thermal efficiency is as high as 80%, at the same time, the total power is low, 40% energy saving.
4. The fuel can be adapted to the coal, oil, 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 single drum dryer and civil investment 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 feed libraries, without cooling.
8.The system uses PLC technology to achieve centralized automatic control, convenient operation and reliable performance.</sup>

Working Principle

^{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 loose 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.}

Applications

^{Red mud drum dryer is not only suitable for drying red mud, but also for the following materials:
Chemical materials: such as ore, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate, etc.
Mining materials: such as large particles and materials with high specific gravity.
Metallurgical materials: such as waste slag and by-products produced during the smelting process of various metals.
Other special materials: such as drying of powder and granular materials with special requirements, such as HP foaming agent, wine lees, light calcium carbonate, activated clay, magnetic powder, graphite, and medicine slag.}
