With the continuous strengthening of the clean utilization policy of coal, the resource utilization of coal slime has become a key link in the green development of the coal industry. As a by-product produced in the coal washing process, coal slime has high water content, high viscosity, difficult transportation, and difficult combustion, which has a huge impact on the environment. How to achieve large-scale, high-efficiency, and low-energy drying of coal slime has become the focus of industry attention.

Among the many drying processes, heavy-duty drum dryers are adopted by more and more large coal enterprises due to their high processing capacity, stable operation, and significant energy saving, and have become the core equipment for achieving coal slime reduction, resource utilization, and harmless treatment.
