But in high hardness material crushing such as cobble, it’s hard to crush them and flat hammer, liner plate even whole crusher will be damaged. In order to avoid this, we usually use cone crusher instead of impact crusher then send the crushed gravel to impact crusher. Though do this will cost more than using impact crusher, but this runs more  steady and maintenance is much less than before, so it will get the best capacity.
