Introduction of three pass river sand drum rotary dryer:

Three pass river sand drum rotary dryer machine 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.The three pass river sand drum 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.

Working Principle of three pass river sand drum rotary dryer:

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.

Application of three pass river sand drum rotary dryer:

Three pass river sand drum rotary dryer is made by our company used on building materials, metallurgy, chemical industry, cement plant for drying of sand, sawdust, wood shavings, chicken manure, iron ore, limestone slag, coal powder, slag, clay stone,etc. This Rotary Drum Drier is composed of rotary body, lifting blade, driving device, supporting device and sealing ring,etc.
