Question

 If it is desired to produce 100 lb/h of the middle cut, calculate the tons of feed required per day?

Solids are being screened using a Mesh 20 screen followed by a Mesh 48 screen. The particle siz
distribution of the feed, coarse, medium, and fine fractions in dry basis is shown in the table. It i
desired to recover all solids with particles sizes range of -20/48.
