The AF cone crusher is a compressive crusher where feed material is crushed between a fixed concave and a movable mantle. Bigger rock particles are crushed against the mantle and concave. This is called single-layer crushing. When smaller rock particles are crushed between other rock particles, it is called multilayer crushing.

A Cone Crusher will deliver a 4:1 to 6:1 reduction ratio. As we set the closed side setting tighter to create a finer output, we also reduce the volume or throughput capacity of the machine. Generally speaking, multiplying the closed side setting by two is a good guide to the top size of the gradation exiting the machine.

An example of the effect that crusher setting has on the product gradation is as follows: If the target crusher setting is 3/8 in. (10 mm) but the setting is not checked and it wears open to 1/2 in. (13 mm), then the end result is a 15 percent decrease in the minus 3/8-in. (10 mm) material size.
