    AP-42 Section 11.19.2 Crushed Stone Processing

    Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen

    Explanation. After secondary crushing stage, oversize material is directed either back to the secondary stage or to be crushed and shaped further at the tertiary stage to get much finer high-quality products. Since the materials are reduced to smaller size, specially designed, strong and faster machineries should be used for tertiary crushing stage

    Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing

    Jul 10, 2020 Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material. There are also tertiary and even quaternary stages of crushing that exist to
