摘要： A gyratory cone crusher includes a first and a second crushing shell defining a crushing gap. The first crushing shell is arranged to gyrate around a vertical axis, in order to crush material entering the crushing gap, and is vertically supported by a thrust bearing including first and second bearing plates defining a spherical sliding interface. One of the bearing plates has one or more cooling and/or lubricating grooves at the sliding interface, each groove defining a channel, extending from the center of the sliding interface to the periphery thereof. In order to obtain a uniform distribution of grooves, the cooling/lubricating grooves are in the form of one or more spirals extending from the center of the sliding interface to the periphery thereof. The disclosure further relates to a bearing plate and a kit of bearing plates involving such a bearing plate.

摘要： 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.

摘要： A gyratory crusher hydraulic pressure relief valve includes a hydraulic fluid vestibule arranged to be fluidly connected to a hydraulic fluid space. A logic element is arranged to dump hydraulic fluid from the hydraulic fluid space, which includes a plunger having a first plunger surface and a second plunger surface, and a control pipe arranged for fluidly connecting the second plunger surface to the hydraulic fluid vestibule. A supply orifice restricts the flow of hydraulic fluid from the vestibule towards the second plunger surface to make the time TC it takes for the logic element to switch from open position to closed position exceed the time TF it takes for a closed side setting position of the crusher to make one full round.
