It is very common for impact crushers or gyratory crushers to be used for this purpose. When the granite is brought to the crusher, typically by a conveyor belt, it will be placed into the crushing area. Through circular impacts, or by impacting it between two separate plates of metal, this rock will begin to break down.

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.
