Coal slurry—a byproduct of coal washing—is characterized by high viscosity and high moisture content. It is prone to runoff when stockpiled, causing environmental pollution; furthermore, its low calorific value and high transportation costs make resource recovery challenging. To meet the specific site conditions and production capacity requirements of a client in Huangling, Shaanxi, the Dingli Group custom-engineered two large-scale DLMG-3632 coal slurry drying systems. With a combined processing capacity of 80 tons per hour, the equipment has been fully installed and commissioned, and is now ready for continuous, stable operation.
The system features an optimized internal lifting structure specifically designed for highly viscous coal slurry. This effectively addresses common industry challenges such as material sticking to the dryer walls, uneven drying, and clogging. It can reliably reduce the moisture content of wet coal slurry from ≤30% to ≤15%, significantly increasing its calorific value and facilitating easier storage, transport, and co-firing—thereby achieving both waste reduction and resource recovery. The system is equipped with comprehensive dust collection, temperature control, and safety interlock mechanisms, ensuring stable operation and manageable energy consumption, well-suited for the large-scale, continuous production demands of mining operations.
From initial design and equipment manufacturing to on-site installation and final commissioning, the Dingli Group provides a complete, one-stop drying solution. This empowers coal enterprises to transform coal slurry waste into a valuable resource, reduce costs, improve efficiency, and advance the development of a green, low-carbon, and circular economy within the mining sector.
