To make a closed-circuit granulation system by a single horizontal rotating conical vessel having the functions of granulation and classification small in scale and simple in operation, a new equipment item, the rotary lifter, was developed in the present work for refeeding small ungranulated particles, which were discharged from the narrow end of the vessel. Large spherical granules as final product were discharged from the wide end of the vessel.<BR>Under various circulating load ratios, closed-circuit granulation of calcium carbonate powder with water was carried out by such a horizontal rotating conical granulator with a rotary lifter. It was experimentally confirmed that more spherical and more uniform size products were obtained in the closed-circuit granulation than the total products in open-circuit granulation by the granulator.
