Difference between revisions of "Cone Crushers"

A '''cone crusher''' is similar in operation to a [[gyratory crusher]], with  less steepness in the crushing chamber and more of a parallel zone  between crushing zones. A cone crusher breaks rock by squeezing the rock  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 (because they are now smaller) 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.

A cone crusher is suitable for crushing a variety of mid-hard and  above mid-hard ores and rocks. It has the advantage of reliable  construction, high productivity, easy adjustment and lower operational  costs. The spring release system of a cone crusher acts an overload  protection that allows tramp to pass through the crushing chamber  without damage to the crusher.
