Machining effects of different mechanical crushers

2015-2-18  Different crushing machines produce different pit and oil drop fragmentation, and the trends confirm that increased pit fragmentation corresponds to increased droplet fragmentation. The data expressed in this research could be used to construct a guideline for the design and sizing of crushing machines with the goal of achieving a balance between pulp fragmentation, pit breakage and oil drop fragmentation.
