ABSTRACT:
Ball agglomerated particulate material is produced by comminuting the material to produce coarse particles having a size predominantly within the range 0.3 mm to 1.4 mm, and fines, then feeding the coarse particles, fines and an agglomerating liquid into a rotating ball agglomerating mill with the volume fraction of the coarse particles being 20% to 80% by volume of the total solids feed to the mill, continuing rotation of the mill until agglomerated balls are produced having a continuous network of fines interspersed with the coarse particles such that: ##EQU1## WHERE .epsilon. = THE POROSITY OF THE AGGLOMERATES,
