Question 2 Ferrochrome pellets are produced in a dryer for use

Question 2 Ferrochrome pellets are produced in a dryer for use in a blast furnace. It is required to reduce the moisture content from 35% to 5% (mass) to ensure that the pellets are strong enough. The total time available for drying is 15 minutes to comply with production demands. Determine the amount of dry material per unit area that can be treated in this dryer. From experimental results, the following data was obtained: Ratio of the rate of drying per unit area to moisture content =34.48kg dry solids /m2hr Equilibrium moisture content of solid is =0.005kg moisture /kg dry solids Critical moisture content =0.15 moisture /kg dry solids [20 MARKS] Question 2 Ferrochrome pellets are produced in a dryer for use in a blast furnace.
