Cone Crusher
The cone crusher is therefore an excellent arrested crusher. The flare of the bowl allows a much greater head angle than in the gyratory crusher, while retaining the same angle between the crushing members. This gives the cone crusher a high capacity, since the capacity of gyratory crushers is roughly proportional to the diameter of the head.

The crushing shell has a fixed cone (bowl liner) and a moving cone (inner crushing cone or mantle). They form the crushing chamber. The eccentric shaft is made from manganese steel alloy. It's powered by the crusher's motor. It rotates in a special way, making the mantle move back and forth. This crushes the material against the bowl liner.
How to Optimize Reduction Ratio in Jaw Crusher?
A high reduction ratio means a higher crushing force and energy consumption, while a low reduction ratio means a lower crushing force and energy consumption. Therefore, it's essential to balance the reduction ratio with other factors, such as feed size, operating speed, and chamber design, to optimize the crusher's performance.
