Abstract

A vertical shaft impact crusher having a rotor (24) mounted for rotation about a vertical axis on a vertical shaft (22) supported by a central bearing, and an impeller mounted on that shaft so that rock fed into the crusher is caught by the spinning impeller and thrown against an adjacent breaker ring (70), and is broken wherein the crusher is provided with guard rings (63, 144, 142, 203) mounted telescopically and concentrically with the vertical shaft (22) forming a labyrinth seal, and also above and below the impeller to restrict the entrance of rock dust and rock fragments to the rotor shaft (22) and bearing and a plurality of upper and lower wear plates which line the impeller to retard its erosion and are designed to be easily replaceable.
