ABSTRACT:
In a rotary pan pelletizer, a central circular portion of the bottom surface of the pan is raised above the level of the annular portion around this central portion, and a stationary central plough is disposed with its lower surface in close proximity to the raised central portion. Binder liquid is fed on to the raised central portion and in operation the central plough keeps the raised central portion substantially clear of build-up of the material to be pelletized, so reducing formation of lumps and stabilizing operation. Further ploughs or scrapers are disposed over the annular portion to maintain a constant level of build-up of material thereon, at substantially the same depth as the height of the raised central portion.
