Coal handleability – rapid on-site assessments

A handleability monitor was designed to provide a simple, rapid, on-site assessment of the whole or part consignment of a coal blend in its "as-received" condition. The monitor was evaluated at a number of coalhandling plants, which handle both metallurgical and power station coals from a variety of sources worldwide. The results can be used to predict which coals could routinely pass through a handling plant at line capacity without causing blockage or delay. Despite extensive analysis of the data, it was not possible to correlate the handleability index to the regular sample analysis of moisture, ash and size analyses of the coal blends.
