Fine Coal - an overview | ScienceDirect Topics

When fine coal is beneficiated by flotation, for example, the wet fine coal need not be dried but may, after filtration, be blended with oil. An ultrasonic treatment after grinding and mixing gives a very stable COW slurry. The need for any stabilizing additives is eliminated. When this fuel burns, the water that is largely contained in or near the coal particles will flash in an explosive …

Ensuring Efficient Handling of Coal & Coke Products

In settings where fines are being conveyed, such as with coal fines or coke breeze, the handling system may not require as robust a system, but rather, a more gentle handling solution. This is often seen with bucket elevators; a continuous belt elevator may be a more appropriate choice over the centrifugal belt style, as the continuous style avoids the throwing action on discharge …
