An air classifier is applied to separate a mixture of four solid waste components shown in Figure 5-20 above. All four components have equal mass.
a) Determine the mass composition in percent of the four components in the
overflow (extract) if the air classifier is operated at an air velocity of 1,000 ft/min.
b) Determine the mass composition in percent of the four components in the
overflow (extract) if the air classifier is operated at an air velocity of 2,000 ft/min
