Find the optimum cyclone size with respect to the fines in pneumatic conveying systems

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 to minimize the cyclone loss rates. Besides the mechanisms of the true gas/solids separation, the production of fines due to particle attrition is identified to affect these two aspects. A first approach of a new design procedure is therefore provided, where an attrition model is implemented in a conventional cyclone model.
