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.
The rotor is the 'heart' of a secondary impact crusher, and the strength of this key component is tested relentlessly by the crushing process. Throughout HAZEMAG's experience of over 70 years of in the industry, special emphasis has always been placed on rotor design, development, and the field of application.

5. Impact crusher Impact crushers can be used for both secondary and tertiary stone crushing. They work by generating high kinetic energy, so the material to be crushed hits a sharp-edged and harder object. Firstly, the material to be broken is accelerated strongly and thrown onto a stationary impact device.
The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms are more efficient in …

They can be used as a primary crusher when the input size isn't too large. They are best used in the later stages of crushing (secondary onwards) as they make a higher spec output than a gyratory crusher. Reduction ratio = 7:1 to 5:1 (depending on size) Impact crushers. Impact crushers can be used at any stage of the crushing process.
In the secondary crushing phase, machines play a crucial role, expertly managing materials from primary crushing. These pieces, usually between 150 to 300 mm, are fed into secondary crushers.
