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.
