Cone Crushing
A Cone Crusher is similar in operation to a gyratory crusher, with less incline in the crushing chamber and a parallel between crushing zones. A cone crusher breaks rock by squeezing it between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner.
As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave. Large pieces of ore are broken once, and then fall to a lower position where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher.
Cone Crushers have the advantage of reliable construction, high productivity, easy adjustment and low operation costs.
