Three pass river sand drum rotary dryer adopts the latest European energy saving technology,clamp type structure. Internal cylinder,middle cylinder and outer cylinder form a since the insulation structure. Special thermal design idea,the emlimination of wind tunnel heat loss,increase the heat exchange area and unit volume evaporation intensity,good energy saving effect.
Application of Rotary Dryer:
The rotary dryer is used for drying sand,yellow sand,slag,clay and other raw materials, widely used in building materials,chemical industry,foundry industry, etc, can adapt to a variety of fuels such as coal, oil and gas.
The heat source of drum rotary dryer comes from the combustion train, and adopts down-flow heating methods. When the materials enter into the body from feeding device, it will be pushed back by the spire raising board. As the dryer is in an inclined position, the materials will be down to the lower end under the influence of gravity and rotation, but the raising board will be threw to the upper end for scattering.
This process make the material well-distributed in the body, then ensure the heat exchanged by heat wind. After repeated cycle with this process, the moisture content can be dried.
Features of Rotary Dryer:
1. Shell adopts assembled structure, and its precision has been improved a lot, which will be convenient for transport.
2. According to different fuel properties, suuitable raising plate will be used. This can make material receive more heat exchange.
3. Sealing is simple but efficient, which can improve capacity and improve whole machine performance.
4. Its matching combustion furnance is energy-saving type, which takes small area and is easy to adjuest.
