A primary crusher reduces the size of the blasted rock. The rock may then be further reduced in size by secondary crushers. Once crushing is complete, screens are used to separate the rock into specific sizes. Rock may be crushed and screened several times before being put in a stockpile with other rocks of the same size. Conveyor belts are used throughout this process to move the rock.
