COOLING SCREW CONVEYOR

Cooling screws from Jiangsu Bootec Environment Engineering Co., Ltd. are designed as pipe or trough screws. They are used in grate firing as well as downstream of fluidized bed and rotary kilns to cool down bulk materials with temperatures of up to 1000 °C for further transport.

The bulk material is conveyed by rotation of the screw shaft. During conveying, cooling water flows through and cools the trough shell and/or the screw shaft.

As a special screw heat exchanger, it is particularly well suited for hot ash cooling in sewage sludge applications.
