Abstract
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.
