ABSTRACT:
A process for producing spherical pellets from stack gas desulfurization residue filter cake. The process includes mixing dry fly ash with a filter cake in a mixer and discharging the blend onto a shallow pan disc pelletizer where pellets are produced. Additional fly ash produces pellets in a reroll ring. Instead of fly ash, cement kiln dust, portland cement, lime kiln dust or lime is utilized.
