The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 6.8).Major suppliers of cone …

— Nip Angle: The nip angle is the angle between the fixed and movable jaw plates. A steeper nip angle means that the crushing chamber is deeper and narrower, which can improve crushing efficiency and reduce the risk of material slipping. However, a steeper nip angle can also increase wear on the jaw plates and require more frequent maintenance.
