Double Cylinder or Double Pass Rotary Dryer FEATURES
In double-shell drums Rotary Dryer takes place in 2 concentric
cylinders. During the transition from the inner drum to the outer
drum, the bulk material’s axial direction of movement is reversed,
meaning that the infeed and outlet for the bulk material are
located on the same side of the double-shell drum.
In comparison to single-shell drums, double-shell drums can be
designed with a larger diameter and a significantly reduced length.
This comes with enormous advantages when it comes to integrating
the dryer or cooler into an existing system.
Double Cylinder or Double Pass Rotary Dryer FUNCTIONALITY
An application-specific design of the internal configuration and
the joint rotation of the inner and outer drums, which are
connected to each other, ensure that there is significant contact
between the loosened bulk material and the hot gas (for drying or
heating up the material) flowing through the drum in a turbulent
pattern or the air (for cooling down the material) flowing through
the drum.
This makes it possible to achieve an extremely intensive transfer
of mass and heat, and, accordingly, very efficient drying or
cooling.
Ideal for: Minerals, sand, slag, ore, coal, clay, bentonite, chemicals,
fertilizers, digestates, waste recycling, refuse-derived fuels
