ZBBSH Series
Three-Cylinder Rotary Dryer
A compact multi-pass rotary drying system for granular industrial materials within the stated moisture and particle-size range.

Operating principle
Configured around the process condition.
The ZBBSH combined three-cylinder dryer routes material through concentric drums to increase the heat-transfer path within a compact footprint. It is intended for granular feed that does not adhere heavily to the drum or lifting elements. Dryer sizing and outlet condition depend on the material, inlet moisture, heat source and required capacity.
