【Application】:A rotary drum drying system for Municipal sewage sludge, papermaking sludge, industrial sludge, etc.
Introduction
The DINGLI sludge dryer machine is designed to reduce the moisture content of municipal and industrial sludge, helping reduce material volume and transportation costs.
Using rotary drum drying technology, the system can be configured to achieve a final moisture content below 20%, depending on sludge characteristics and operating conditions. It is suitable for sludge drying applications requiring further treatment or disposal in accordance with local regulations.
Principle
Wet sludge enters the rotating drum and is continuously exposed to hot air. Moisture evaporates as the material moves through the drum, and the dried sludge is discharged for further processing.
The system mainly consists of a hot air furnace, feeding equipment, rotary drum dryer, discharge conveyor, induced draft fan, dust collector, deodorization equipment, and electrical control cabinet. The configuration can be customized according to sludge type, processing capacity, moisture requirements, and heat source.
