The foam coal upgrading dryer is a specialized drying equipment used for processing foam coal materials. Its main function is to reduce the moisture content in foam coal through high-temperature or low-temperature hot air drying processes, thereby improving its quality and calorific value. The foam coal upgrading dryer usually adopts a drum structure, with internal dispersing and lifting devices to ensure that the material is in full contact with hot air and achieve uniform drying.

Working principle

The working principle of the foam coal upgrading dryer is to fully contact the foam coal material with high-temperature or low-temperature hot air, and quickly evaporate the moisture in the coal using the principle of heat exchange. The specific process is as follows:

Foam coal is fed into the drum dryer through feeders and conveyors.

In the drum, the foam coal is in full contact with the hot air, and through the action of the dispersing device and the lifting plate, a uniform material curtain is formed.

The heat generated by the hot blast stove is transferred to the coal, completing the drying process.

The dried coal flows out of the receiving hopper and is transported to the storage location by the conveyor.

Application scenarios and advantages

Foam coal upgrading dryer is widely used in the coal processing industry, suitable for drying various coal materials such as coal slurry, clean coal, raw coal, coking coal, lignite, etc. Its advantages include:

Efficient drying: By using high-temperature or low-temperature hot air drying, the moisture content of coal can be quickly reduced.

Uniform drying: The built-in dispersing and lifting device ensures uniform heating of the material, resulting in a significant drying effect.
