Tertiary crushing is the final stage in the comminution process, where the product from the secondary crushing stage is further reduced in size to a finer product size. The purpose of tertiary crushing is to produce a high-quality end product that is suitable for use in various applications, such as concrete production or road construction.
Crushing is the process of fragmentation mineral grain aimed at achieving a certain grain size distribution, grain shape and mineral liberation (Salopek & Bedeković, 2000). The quality of building crushed stone is evaluated on the basis of the physical and mechanical characteristics, the grain size distribution and the grain shape.
