Which is better for the blast furnace process, sinter or ...

Why do we use sinter up to 50%, but pellets 15-20% in blast furnaces? For three reasons. One, Pellet swells after heating. Swelling is upto 200% by volume. This increase in volume reduces permeability of ascending gases inside furnace. Secondly, sinter being irregular in shape offers more permeability than pellet beacause of round shape of pellets.
