Abstract
A method of forming spherically shaped pellets of relatively small diameter is disclosed which comprises the steps of depositing a finely divided congealable material on a surface of a disk shaped body, transporting the body over a closed course which extends in a plane forming an acute angle with the horizontal while rotating the body during the transport in the plane of the course thereby imparting a tumbling motion to the material and resulting in the fabrication of pellets, and collecting pellets of a predetermined range of sizes. A pelletizing apparatus is described which is adapted for forming pellets of relatively small diameter having enhanced surface characteristics and for automatically classifying the pellets by size.
