The secondary crusher is the equipment that reduces the size of the materials further, after they have been reduced by the primary crusher. The secondary crusher has a size reduction ratio ranging from 3:1 to 5:1. The secondary crusher can be a cone crusher, impact crusher, or gyratory crusher, depending on the hardness, abrasiveness, and size ...

In the working process of the machine, the rotor rotates at a high speed driven by the motor. When materials enter the crushing chamber, they will be impacted and crushed by the blow bar on the rapidly turning rotor, and then thrown to the impact plate for a secondary breaking, finally rebounded back to the rotor area and be crushed again.

In most cases, two or more secondary crushers are necessary to obtain the same throughput as the primary crusher. To lower wear and tear and energy consumption in the secondary crushers, the product of the primary crusher should be screened and only the fraction coarser than the final grain size should be fed to the secondary crusher.

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.
