The lignite drying system mainly consists of a heat source, dispersed feeding, belt feeding machine, drum equipment, unloader, dust removal equipment, belt discharge machine, induced draft fan, and power distribution operation.

1.Raw material crushing and loading system (optional):
For raw materials that are too large, crushers will be needed to crush the lignite to meet the particle size requirements. In order to achieve fully drying of the lignite, the feed particle size is about 20-50mm.

2.Combustion heating system:
Use pulverized coal injection furnace, pulverized coal silo, air flow conveying and other equipment to ensure that a stable high-temperature heat medium is provided to the drying system.

3.Drying and dehydration system:
Use sealed feed box, anti-tempering chute, rotary drum dryer, discharge box and other equipment to complete the mass and heat exchange between high-moisture lignite and high-temperature hot air.

4. Environmental protection dust removal system (optional): Cyclone dust collector, explosion-proof bag dust collector, induced draft fan and other equipment are used to recover fine particles in the dried and achieve tail gas emission standards.

5. Power distribution and control system (optional):
PLC automatic control system, complete power distribution device, local box, video monitoring system and other electrical equipment are used to achieve the control and monitoring of the drying system.

6.Product conveying system:
Use belt conveyor to transport the dried products to the user’s designated location.
