Abstract: An anti-segregation mixer for a bed of material, the anti-segregation mixer comprising: an elongate and substantially cylindrical shell having an inner surface; and a plurality of independent lifting means provided within the shell, wherein the plurality of lifting means each comprise a vane with a leading end and a trailing end, and are arranged with respect to the cylindrical shell such that the vane is spaced apart from the inner surface and the entire lifting means may pass through the bed of material.

Abstract: There is provided a dispersion apparatus for use with a solid fuel burner. The dispersion apparatus comprises a passage through which particulate material may flow toward an outlet region for dispersal therefrom, the flow being at least in part rotational about the longitudinal axis of the passage. The dispersion apparatus also comprises a downstream guide means arranged within the passage at or near the outlet region, the downstream guide means configured to at least reduce the rotational motion so that the flow progresses toward the outlet region in a substantially uniform manner in a direction aligned with a longitudinal axis of the passage.

Abstract: A method for the maneuvering of a vessel, such as a dredge, stacker, barge or wet concentrator plant, the vessel having provided thereon at least four winches from which winch ropes extend to anchor points located remotely from the vessel, the winches being operable to maneuver the vessel, wherein at least one winch is kept under a defined torque whilst three winches are utilized to control the movement of the vessel. A maneuvering control system for implementing the method of maneuvering described is also disclosed.
