The fluidization behaviour of ignimbrite at high temperature and with mechanical agitation [PDF]
, 2004 Experiments were carried out to study the fluidization behaviour of ignimbrite at high temperature and while being mechanically agitated. Geldart group C behaviour occurs up to 565 degreesC when the material is subjected to increasing gas flow ( without ...
