Abstract
An improved cone crusher wherein raw material is crushed between a gyrating mantle and a bowl liner above the mantle. Space between the mantle and the bowl liner is adjusted by moving the bowl liner upward, and the adjusting movement is automatically performed by hydraulic pressure applied evenly to the entire circumference, successfully meeting fluctuation of load and abnormal overload.
