Gyratory Crusher an overview ScienceDirect Topics

The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment).. This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.
