ABSTRACT:
Rolls 9, 10 for a compacting mill 5 by which finely divided agglomerative material 6 is compacted into a sheet 7 produce a pattern of slots 23 in the opposite surfaces of the sheet 7 whereby the sheet is encouraged to fracture into tablet-like bodies 8 of uniform size and shape. The slots 23 are defined by uniformly spaced ridges 21 on the rolls 9, 10, the ridges 21 on one roll 9 or 10 extending transversely to those on the other roll 10 or 9. Preferably the ridges 21 extend circumferentially on one roll 9 and axially on the other roll 10. A form for the ridges 21 is described that enables their easy and complete withdrawal from the slots 23 in the sheet 7 and encourages the sheet 7 to fracture on the medial plane of every slot 23.
