Two different design aspects for cyclones are considered. The first aspect
is to keep the product as free of fines as possible and the second one is t
o minimize the cyclone loss rates. Besides the mechanisms of the true gas/s
olids separation, the production of fines due to particle attrition is iden
tified to affect these two aspects. A first approach of a new design proced
ure is therefore provided, where an attrition model is implemented in a con
ventional cyclone model. (C) 2000 Elsevier Science S.A. All rights reserved
