3. Efficiency and quality of industrial classification

3.1 Relationship between yield and mass balance

If we consider a pneumatic classification operation (figure 1 ) with :

• M, M _g and M _f the mass flow rates of separator feed, coarse product and fine product respectively;

• is the size of the particle ;

• F (a), F _g (a) and F _f (a) the cumulative distributions of a-dimensional particles in the feed, coarse product and fine product respectively;...
