The output from the secondary crusher and the throughs from the secondary screen are transported by conveyor to the tertiary circuit, which includes a sizing screen and a tertiary crusher. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers.

  • Dust emission from crushing of hard rock aggregates

     · Tertiary crushing generated two to three times as much PM 2.5 (130–200 μg/m 3) compared to secondary crushing (70–80 μg/m 3). The largest number of samples exceeding the measurement capacity was found in Quarry 6, where the number of crushing units was the highest (tertiary crushing with four crushing units).
