Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32 from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 1.7 = 78 cm.

Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive.

Nov 12, 2019 Because the jaw crusher is intermittent working, divided into work stroke and idling stroke, resulting in the motor load imbalance. In order to balance the load, the energy of the idle stroke is accumulated when the moving jaw leaves the fixed jaw, so that the energy can be fully released during the working stroke.
