Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap between the bowl liner and the mantle narrows, the rock is

The linings are carefully designed to maximize the availability of your mill and keep your costs to a minimum. This combination allows the use of more wear resistant alloys of iron and steel than can be used in a conventional metallic lining, as the rubber substantially dampens the impact forces and also results in a lower lining weight.
