  The Purpose Of Using An Aggregate Crushing Machine

  Dec 29, 2019 · Since the purpose of using aggregate crushing machines is to break the rocks down to sizes that you would prefer, it is likely that you will need at least two different machines for this process. Some of them are only able to break down larger rocks into mediumsized components. You will need a secondary machine to do the rest.

  Calculation and Result The aggregate impact value (AIV) is: AIV = (B/A) X100 (%) . . . (1) An average is taken of the two tests and the result is recorded to the nearest whole number as the Aggregate Impact Value. The AIV is normally about 105 per cent of the Aggregate Crushing Value and it can be used for the same purpose.
