A
cone crushing plant is similar in operation to a gyratory crushing plant, with less steepness in the crushing plant chamber and more of a parallel zone between crushing plant zones. A cone crushing plant 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 crushing plant, 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 crushing plant.
A
cone crushing plant is suitable for crushing plant 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 crushing plant acts an overload protection that allows tramp to pass through the crushing plant chamber without damage to the
crushing plant.
