1. Product Description
The energy-optimized coal slurry and fine mineral powder drying production line is a complete continuous industrial drying system specially developed for high-moisture viscous materials such as coal slurry, slime, fine ore powder, mineral tailings and sludge. The whole production line integrates feeding, crushing, dispersing, heat exchange drying, dust removal, waste heat recovery, finished product collection and automatic control. It adopts targeted energy-saving design to solve the technical difficulties of easy adhesion, agglomeration and low thermal efficiency during the drying of fine granular mineral materials. It can stably adjust the final moisture content of finished products to meet the requirements of subsequent transportation, storage, incineration and deep processing, and is widely used in coal washing plants, mineral processing plants, metallurgical enterprises and solid waste resource recovery projects.
2. Working Principle
Wet raw materials including coal slurry and fine mineral powder are stably transported to the dispersing unit by the feeding system. Bulk agglomerated materials are broken up to avoid material bonding inside the drying host. High-temperature hot air generated by the heat source device enters the drying chamber and conducts sufficient convective heat exchange with continuously stirred and suspended materials. Moisture inside the materials evaporates rapidly under the action of heat. The produced humid flue gas is delivered to the dust removal system to capture fine dust, and part of the low-temperature waste heat is recycled and reused through the energy optimization loop to reduce fuel consumption. After reaching the set moisture standard, dry materials are discharged from the outlet, and the finished product conveying system sends dry coal powder and mineral powder to the designated storage area. The whole process operates under closed negative pressure to prevent dust leakage.
3. Core Features
Systematic energy optimization design with waste heat recycling module, effectively lowering comprehensive heat consumption and operating cost.
Special material dispersing and anti-sticking structure, greatly reducing material adhesion and blockage inside the drying equipment.
Modular layout design, supporting flexible matching of heat sources such as coal-fired hot blast stoves, natural gas burners and waste heat flue gas.
Closed negative pressure operation structure, excellent dust suppression effect, complying with environmental protection emission standards.
Intelligent automatic control system, real-time monitoring of material temperature, exhaust gas temperature and finished product moisture, realizing stable and unattended running.
Wide adaptability, suitable for continuous drying of various high-viscosity wet materials: coal slurry, slime, fine mineral powder, tailings and industrial sludge.
