The coal slurry drying project in Huangling, Shaanxi—undertaken by the Dingli Group—has successfully completed on-site installation and integrated commissioning. The project has now entered the final stage of preparation for full-scale production, serving as a new benchmark for the resource utilization of solid waste within the local coal industry.
Designed specifically to handle highly viscous coal slurry, this drying system features an optimized internal lifting structure. It effectively addresses common industry challenges such as material sticking to the walls, uneven drying, and clogging. With a processing capacity of 80 tons per hour, the system can reliably reduce the moisture content of wet coal slurry from ≤30% to ≤15%. This significantly increases the calorific value of the coal slurry, facilitating easier storage, transport, and co-firing, while achieving both the reduction and resource recovery of solid waste. The complete system is equipped with comprehensive dust removal, temperature control, and safety interlock mechanisms, ensuring stable operation and controllable energy consumption—perfectly suited for the large-scale, continuous production requirements of mining operations.
Leveraging years of expertise in coal slurry drying technology, the Dingli Group provided a customized drying process solution for the client. The coal slurry dryer incorporates a specialized anti-sticking design, enabling it to handle high-moisture, viscous material with uniform drying and consistent output. The system also integrates intelligent temperature control and a negative-pressure dust removal network, balancing production efficiency with safety and environmental compliance. Once operational, the wet coal slurry is transformed into a high-quality fuel—turning waste into a valuable resource. This helps the client reduce solid waste disposal costs and increase revenue from resource recovery, all while meeting stringent environmental regulations.
Deeply rooted in the field of solid waste drying, the Dingli Group provides customized, end-to-end coal slurry drying equipment and EPC (Engineering, Procurement, and Construction) services to clients in the coal, coal-chemical, and coal-washing sectors. Through its mature drying technologies, the company empowers industrial and mining enterprises to achieve a green transition, improve energy efficiency, and boost operational performance.
