Coal Drying Methods
Coal Drying Methods. In the past, it has more or less been a general rule that any time the total product is being washed, both mechanical and thermal drying was required. The reason for this was that a product moisture of 3 to 4% was required and thermal drying was and is the only practical method by which this can be accomplished.

Drying of coal slurries, so far, is not very common. In Germany, for example, a rotary (kiln) dryer was used with fluidized bed combustion for drying coal concentrate obtained from flotation beneficiation of coal slurry and coal with a moisture content below 3% was supplied as fuel for cement plants and as a reducing agent for blast furnaces. In Russia, there was cited an example of coal slurry drying for the …
Microwave Drying of Moist Coals - ResearchGate
Physical principles and examples of practical implementation of drying large bodies of coal by microwave radiation are considered. It is shown that energy consumption in microwave drying of brown coals decreases to 1.5–1.8 (kW·h)/ kg as compared with traditional types of drying, for which the expenditures of energy amount to 3.0 (kW·h)/kg.
Drytech Engineering | Drying Technology
Drytech has identified four different methods of drying/processing concentrate materials, namely: flash drying; spraydrying; conveyor drying; rotary drying; and have proven installations of these systems. Advances in technology have convinced Drytech that flashdrying or spraydrying are preferred and recommended for drying mineral concentrates, but they have also continued to progress conveyor and rotary drying …
Solid–liquid separation technologies for coal - ScienceDirect
Separating the drying process by mass-transfer is another interesting trend, particularly for drying, whereby the thermal drying process is applied to an external medium, which allows drying the coal without the application of heat as the medium is taking up the water from the coal, can be separated and separately dried.
