jaw 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..crusher - wikipedia,its way of working consists on a bucket with two crushing jaws inside, one of them is fixed and the other one moves back and forth relative to it, as in a jaw crusher. they are manufactured with a high inertia power train, circular jaw movement and an antiestagnation plate, which prevents large shredding pieces from getting stuck in the bucket's mouth, not allowing them to enter the crushing jaws..
