| Abstract: | The spherical agglomeration process is a means of size enlargement in which agitated particles, suspended in a liquid, are bonded together by a second liquid, which will wet the solid surfaces and be immiscible with the suspending medium. A process is described in which agglomeration takes place in a cone shaped vessel, rotating horizontally about its symmetric axis. The cone configuration of the agglomerator imparts a longitudinal impulse to the charge, which is most effective on the largest particles. This causes a size classification within the cone, with the largest agglomerates congregating at the base. The result is the continuous production of uniformly sized, highly spherical pellets. The factors affecting agglomerate growth and size are outlined and discussed. |
