• Crushing for particle shape AggMan

    Nov 17, 2014· Typically, when crushing aggregates for particle shape, the desired output is a cubical product. In concrete production, a cubical aggregate product requires less water and cement than a flat and elongated product. Similarly, with asphalt production, cubical aggregate requires less asphalt binder.
