Triple Pass Rotary Drum Dryer

The triple-pass drum consists of three concentric cylinders that are supported from the heads on

either end in a manner that allows them to expand at different rates relative to each other.

The material is fed into the inner cylinder, passes to the middle cylinder and then to the outer

cylinder passing a rolling motion and forming a stable product.

Each concentric cylinder of the triple-pass drum is equipped with heavy-duty flights for raising the

material and showering it through the drying gas stream as the drum is rotated.

The triple-pass drum is equipped with three  temperature sensors at the drum outlet. The

temperature sensors are interlocked with the burner controls. A drum inlet water spray

extinguishing system is also interlocked with the sensors. An exit gas stream temperature in

excess of 240°F activates the inlet water spray extinguishing system. The drum inlet is also

equipped with a temperature sensor. The inlet is interlocked with the burner management panel

to shutdown the burner if the inlet temperature exceeds 1600°F.
