Abstract

A solids handling equipment rotary plough (200) includes an elongate metal body (201) with a leading face (210) and a trailing face (212). The body (201) is configured to be mounted to a rotary component for rotation about an axis of rotation at least in one direction which is an operative forward direction such that the leading face (210) leads the trailing face (212). At least the leading face (210) has at least two major operatively upwardly and outwardly extending surfaces (202.1, 204.1) which are not coplanar. A first major surface (202.1) is angled operatively rearwardly and upwardly relative to the forward direction of rotation at an angle of at least 1° to the vertical. A second major surface (204.1) is angled operatively forwardly and outwardly at an angle of at least 1° relative to a radius of a circle described in use by the rotary plough (200) when rotating in the operative forward direction.
