Working Principle

The coal drum dryer is a downstream drying process equipment, consisting of a hot blast stove, belt feeding machine, drum dryer, belt discharging machine, induced draft fan, cyclone dust collector, bag filter (or wet dust collector), and operation control system. The working principle of this equipment is as follows:

1.In the feeding area, the coal is quickly exchanged with the high-temperature and hot air, resulting in the evaporation of moisture. The material is then guided by a large angle guide plate and sent to the workspace.

2.In the copy plate area, the coal forms a curtain-like material that is in contact with the hot air. The moisture in the coal rapidly evaporates and becomes water vapor, which is siphoned off by the induced draft fan, resulting in coal drying. The moisture of coal in this area is less than 15% (or less) under a state of looseness. After heat exchange, the material achieves the required moisture state and is discharged out.

3.The discharging area does not have a copy plate roller. The material in this area scrolls and taxis to the discharge port, completing the whole drying process. Equipment can be customized according to the customers' requirements.
