    The product shape is more easily controlled and energy is saved by the removal of particles once they have reached the size required. Large impact crushers will reduce 1.5 m top size ROM ore to 20 cm, at capacities of around 1500 t h −1, although units with capacities of 3000 t h −1 have been manufactured. Since they depend on high velocities for crushing, wear is greater than for jaw or gyratory crushers.

    5/13/2019· Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 percent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.

    Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.
