Impact Crusher

Impact crushers provide better grain size distribution of RA for road construction purposes and they are less sensitive to material that cannot be crushed such as steel reinforcement Generally jaw and impact crushers exhibit a large reduction factor defined as the ratio of the particle size of the input to that of the output material.
