Abstract
A gyratory crusher includes a flexible dust seal having an outer edge attached to a cone head of the crusher and to an outer of a ball-bearing seal, an inner race of which is attached to a mounting arrangement for rotationally mounting an eccentric member about a crusher axis with a pair of taper bearings and for rotationally mounting the cone head about a cone head axis offset from the crusher axis. The cone head is also mounted on a plurality of hydrostatic bearings. A mantel of the crusher is attached to the cone head by a removable cap nut and mantel stud. The crusher includes a self-contained lubricating system and a hydraulic tramp iron relief system with connections contained internally within structure of a lower frame portion of the crusher. The crusher includes a drive gear centered about the crusher axis and attached directly to the eccentric member. The crusher also includes a thermal relief system adapted to transfer thermal energy from the mounting arrangement to the lower frame portion connected to the mounting arrangement.
