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 ...
