ABSTRACT:
A method of obtaining a measure of the stickiness of heated particulate solids (40) includes pouring a sample of the particulate solids (40) onto a generally horizontal support (12) and allowing it to freely form its own angle of repose. The sample is subjected to a predetermined heat and gas atmosphere regime, and the support is rotated about a generally horizontal axis to an angle (42) where the integrity of the sample (40) fails. The angular position (42) is a measure of the stickness of the particulate solid (40).
