Color will vary depending on the type of rock from which it was made. Crushed gravel, on the other hand, is produced by the natural processes of weathering and erosion, and typically has a more rounded shape verses the angular surfaces of stone. This material comes in sizes generally ranging from less than a half inch up to 20” in diameter.

Process Of Crushing Rock In Aggregate. 2019-3-1This confirms the observations that the number of crushing units influences dust emissions. The increase in the number of crushing units yields the smallest particle size of the aggregate and increases the timespan in which the rock material is within the process and therefore, it increases the dust emission from the crushing.
