What Is Primary, Secondary, and Tertiary Crushing?

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 ...

Crushing & Screening Plant Design Factors

The jaw crusher is the simplest and most fool-proof of secondary crushers. Rolls are often used where the shearing action of a roll crusher and a minimum amount of slimes are desired. However, rolls ordinarily should not be used to produce a feed finer than 1/8" and a reduction of 4 to 1 should be the maximum between the feed and discharge.
