"Zhonghui Machinery provided a complete turnkey drying solution that fully met our production targets. The equipment operates reliably, the drying performance is excellent, and fuel costs have been significantly reduced by utilizing our own coal as the heat source. We are satisfied with both the equipment quality and the professional technical support throughout the project."
Vietnam Coal Group, one of the country’s leading coal producers, required an efficient solution to process large volumes of wet coal before storage and further utilization. High moisture content reduced calorific value, increased transportation costs, and affected production efficiency.
To improve product quality while reducing operating costs, Zhonghui Machinery designed and supplied a 2,000 TPD rotary coal drying production line. The customized solution significantly improved drying efficiency, stabilized coal quality, and enabled continuous industrial-scale production while meeting local environmental requirements.
The complete production line was engineered according to the customer’s material characteristics and production targets. The system combines a high-capacity rotary drum dryer with a self-fuel fluidized furnace to provide continuous and energy-efficient thermal processing.
Main equipment includes:
The integrated configuration supports stable 24-hour continuous operation with low maintenance requirements and optimized fuel consumption.
The production line adopts a mature continuous drying process to maximize drying efficiency and minimize energy consumption.

The automated process ensures uniform heat transfer, stable moisture reduction, continuous production, and environmentally compliant dust treatment.
Designed for 2,000 tons per day, supporting continuous industrial-scale coal drying.
The fluidized furnace uses the customer’s own coal as fuel, greatly reducing external energy consumption.
Advanced heat exchange and lifting structure ensure uniform drying and consistent moisture content.
Integrated conveying, temperature control, screening, and dust collection systems minimize manual intervention.
Efficient dust collection and emission control help the production line comply with environmental regulations.
Complete engineering, installation, commissioning, and technical support ensured rapid project startup and stable long-term operation.
