Determining if the Mass Loading Effect will Occur

4 Determining if the Mass Loading Effect will Occur 

Next we determine whether the mass loading effect (saltation) will occur. According to the MM, the amount of solids that the gas phase can hold in turbulent suspension upon its entrance into a cyclone depends on the mass average (the median) particle size of the feed, the cut-point of the inner vortex, X50, and, to a lesser extent, on the inlet loading itself, Cq. This limiting or limit-loading is  

we will determine the overall separation efficiency for saltation conditions, i.e. when Cg Col- This efficiency includes the efficiency due to saltation in the inlet and the efficiency due to classification in the inner vortex. A portion of the incoming solids that is not collected by the former is collected by the latter, so that the total efficiency becomes (see also Chap. 9)  

In addition to the normal feed particle size distribution that enters the cyclone, Muschelknautz and co-workers (Muschelknautz and Trefz, 1990,1991 Trefz, 1992) have modified their earlier cyclone model (or models) to include an inner feed or inner feed particle size distribution . The concept here is that, if the inlet solids loading exceeds the limit loading , some portion of the incoming feed solids will quickly separate out but those that don t will have a somewhat finer particle size than that feeding the cyclone. It is this
