Primary jaw crushers are typical of the square opening design, and secondary jaw crushers are of the rectangular opening design. A Jaw Crusher reduces large size rocks or ore by placing the

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 crusher 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 ...

As regards primary crushing machines, the choice is limited to two types—the jaw crusher and the gyratory. The jaw crusher is, of course, a reciprocating-action machine, crushing rock by direct pressure between a fixed plate and a swinging jaw.

Primary Secondary Sizers McLanahan

Primary and Secondary Sizers are sized and selected based on the specific material and lump size to be crushed. Tooth profile selection allows the material to be grabbed and pulled into the crushing zone for maximum efficiency. Sizers use an electric motor to drive the gear reducer, which is mounted directly to the crushing shaft.
