Pros. Impact crushers are capable of delivering a much more homogenous, consistent and cubical end product. This makes impact crushers favourable when the final result needs to be a saleable commodity. Moreover, impact crushers can be highly efficient. They also use comparatively low energy compared with other crushers types.
