These are bolts that have a known shear strength. If something that the crusher cannot crush accidentally gets into the crushing chamber these bolts will shear off when the Jaw hits the unbreakable object. This will prevent damage to the rest of the crusher. Unlike the gyratory crusher the main lubrication used on Jaw crushers is …

The nip angle is affected by the distance between the rolls. The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface characteristics of the rolls. Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°.

A larger feed opening increases material intake and ensures that the rocks enter the jaw crusher's cavity without restrictions. A steeper nip angle decreases operating costs by reducing wear on jaw dies and speeds up material flow down in the cavity. The stroke is amplified from top to bottom, leading it being longest in the bottom of the cavity.
