A secondary crusher is a machine designed to break down large rocks or other materials into smaller pieces for further processing. Typically, secondary crushers are used in conjunction with ...
When a horizontal impact crusher is processing material, the aprons inside serve as supplemental points of impact as the material is smashed against them by the rotor's blow bars. To ensure an impact crusher is operating at its most productive rate, it is valuable to take the time to configure the primary and secondary aprons so that they are …
Secondary impact crushers are vital tools in the aggregate and mining industries, designed specifically for the second stage of crushing. After the initial reduction by a primary crusher, these machines take the coarser input material and further reduce it to the desired size, shaping the particles into a more cubical or uniform form. They are particularly …

Cone crushers and gyratory crushers are mainly used as secondary crushers in a crushing plant. Crushed product from the primary crusher (usually Jaw Crusher) is fed through the top of the cone crusher and flows over the mantle. A vertical drive shaft rotates the mantle eccentrically below the bowl liner, squeezing the product and crushing it ...
Secondary impact crushers are crushing machines designed to process middle-size stone products into gravel or sand-sized aggregate. Impact crushers differ from other crushing machines in that they utilise impact as the mechanism of crushing, rather than the pressure force employed by other kinds of crushers. Commonly found in a range of mining ...

This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.
