Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing

Crushing Equipment / March 11, 2023 / 5 minutes of reading. An impact crusher is a machine used to crush materials by impact energy. It works by feeding the material into a rotating rotor, which is equipped with a series of hammers. As the rotor spins, the hammers strike the material, causing it to break into smaller pieces.
