Coal handleability - rapid on-site assessments

A handleability monitor was designed to provide a simple, rapid, on-site as sessment of the whole or part consignment of a coal blend in its "as-receiv ed" condition. The monitor was evaluated at a number of coal-handling plant s, which handle both metallurgical and power station coals from a variety o f sources worldwide. The results can be used to predict which coals could r outinely pass through a handling plant at line capacity without causing blo ckage or delay. Despite extensive analysis of the data, it was not possible to correlate the handleability index to the regular sample analysis of moi sture, ash and size analyses of the coal blends.
