Coal is very friable (breaks easily) so you do not need the force a cone crusher can supply. Also a cone will create more fines than a roll crusher. Another factor being that both roll crushers and impactors take up less height than a cone so the overall height can be less.
Compression Crushing: Compression crushing, also known as compressive force, applies a compressive force to the material between two surfaces until it breaks.This way is frequently applied in jaw crushers and cone crushers. In jaw crushers, the material is squeezed between the fixed jaw and the moving jaw.
