Why cone crusher should be selected for hard rock crushing

Hard rock, as the name suggests, refers to rocks with a harder texture, such as granite, basalt, etc. For the crushing of this type of hard rock, jaw crusher, impact crusher, and cone crusher can often be used. However, from the comparison and analysis of crushing efficiency, finished particle shape, and wear rate, cone crusher is more suitable for the crushing operation of hard rock. The specific introduction of knowledge related to hard rock fragmentation is as follows:
