Crushing 101 – Different types of crushers for distinctive needs
Impact crushers are traditionally classified into 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.
