1.9–76.0 t/h drying capacity range
Rotary drum dryer production line
60% lower power consumption
Compact, stable, and efficient operation
Zhenggang Machinery configured a rotary drum dryer production line using a rotary drum dryer, belt conveyor, bucket elevator, feeding hopper, feeding pipe, discharge conveyor, and dust collection system. Wet materials are conveyed to the dryer hopper by belt conveyor or bucket elevator, then enter the rotary drum dryer through the feeding pipe. Inside the slightly inclined rotating cylinder, the wet material contacts hot air or flue gas to complete drying. The improved feeding and discharge structure helps reduce blockage, uneven feeding, material return, and dust collection pressure while improving drying efficiency and operation stability.
Wet material properties, moisture content, site layout, and capacity requirement evaluation
Rotary drum dryer, conveying, feeding, discharge, and dust collection system design
Dryer cylinder, conveyor, bucket elevator, feeding system, and dust collector installation
Operator training for dryer control, final moisture adjustment, dust system, and maintenance
The project was implemented through material analysis, site layout planning, equipment configuration, manufacturing, installation, commissioning, and operator training. Zhenggang Machinery designed the drying and calcination process line according to the customer’s material moisture, capacity requirement, and final moisture target. This structured implementation helped the customer achieve stable feeding, efficient drying, reliable discharge, and cleaner production.
After installation and commissioning, the rotary drum dryer process line provided stable drying performance with lower energy consumption, compact layout, and reliable operation. The system helped reduce floor space, civil construction investment, and power consumption while improving heat transfer, material adaptability, and drying efficiency. The improved feeding and discharge structure reduced blockage, uneven feeding, and material return. The dust collection system also helped capture particles from exhaust gas and supported cleaner industrial production.
