Product Features & Applications

Hollow blade dryer is a continuous drying equipment with indirect conduction heating and low-speed mixing, specially designed for deep sludge drying and solid waste reduction. It is often used together with decanter centrifuge to further dry sludge from 75%–85% moisture content to below 30%, realizing significant sludge reduction, harmlessness and recycling. It is the core drying equipment for municipal sewage, industrial wastewater and sludge treatment systems.

The dryer adopts a horizontal W-shaped closed structure with dual-shaft hollow wedge blades inside. Heating medium (steam/thermal oil/hot water) enters the shell jacket and blades simultaneously to heat materials indirectly through metal walls. After wet sludge enters, the blades rotate at low speed to stir, push and continuously update the heat transfer surface for fast moisture evaporation. The wedge blades have self-cleaning function to prevent wall sticking. The whole machine runs closed with centralized collection of vapor and odor.
