ABSTRACT:
This disclosure relates to method for forming a carbon anode block using apparatus comprising a movable mold, a feedbox extendable to a position where it is directly above the movable mold, a stationary bolster encompassed by the movable mold, a vibration means attached to the stationary bolster, and a movable press ram mounted for motion in the vertical plane above the stationary bolster and having protrusions extending from the face thereof. Aggregate used in forming carbon anodes is discharged into the feedbox and the feedbox and mold then move upwardly leaving the aggregate contained within the mold. The feedbox is then removed and the vibration means activated to compact the aggregate by expelling the air therefrom. During the compaction of the aggregate, the press ram is brought downward in proximity to the upper surface of the aggregate with the protrusions in the face thereof extending into the aggregate, and control means then continue to move the press ram downward in response to means which sense the compaction rate of the aggregate whereby the aggregate will form about the protrusions during compaction with substantially little or no pressure being applied by the press ram.
