Inquiry Online Contact UsCreated during the crushing and drying phases of coal mining, coal fines particles smaller than 6mm present disposal issues, as well as pose a health hazard to personnel and a contamination risk to the site. However, if processed correctly, coal fines can be converted into a fuel source, making them a valuable commodity.
Numerous drying technologies have been proposed for drying coal they include pulse combustion, vacuum, fluid bed, rotary, flash, microwave, and superheated steam drying. Each technology has some pros and cons, which are not always clearly spelled out in the literature.
There are a few power plants around the world using one or other of the available drying methods to reduce the coal moisture, there are also trials underway at power plant sites and at laboratories to find the most appropriate technologies for coal drying.
