  • Adr A Classifier For Fine Moist Materials Bentham Science

    MSWI-bottom-ash IBA and CampD-waste CDW are notoriously difficult to classify or separate at grain sizes below 12 mm. The problem is caused by the combined presence of -1 mm fines and moisture, which act together to form agglomerates and foul screens and other separation equipment. Results are presented of an experimental study into the separation performance of a new type of classifier ...
