The impact crusher is a highly efficient coarse, medium and fine crusher for medium-hard and softer rocks. Whether in a quarry, mining or Construction waste recycling, the impact crusher can efficiently crush the stone, so that the particle shape, particle size distribution and cleanliness are in line with the strict standards of concrete and asphalt aggregate.
