Abstract

See full text

A hydraulic system for controlling the position of a movable jaw of a jaw crusher includes a hydraulic cylinder having a piston with a piston rod for positioning the movable jaw. The hydraulic cylinder has a bore side space for containing a hydraulic fluid taking up crushing forces exerted by the movable jaw on the piston rod, and an annular side space containing a hydraulic fluid pressing the piston against hydraulic fluid of the bore side space. The hydraulic system further includes an annular side space accumulator having a fluid compartment, which is in fluid contact with the annular side space, and a gas compartment containing a pressurized gas applying a pressure on the hydraulic fluid in the annular side space.
