  • Crushing for particle shape - AggMan

    If a deposit tends to produce an end material that is flat and elongated, compression crushing may exacerbate the problem by creating a more angular particle. A higher reduction ratio also will produce a more angular aggregate product. "Some form of rock-on-rock crushing is usually required to make a cubical product," Estes notes.
