Abstract
Apparatus for cleaning contaminated aggregate includes at least one channel arranged in use to receive a liquid containing contaminated aggregate; and first and second banks or groups of at least one jet. The first bank or group of jets is arranged to direct pressurized fluid at the contaminated aggregate in order to agitate the contaminated aggregate against a surface and promote the separation of cleaned aggregate from contaminated aggregate. The second bank or group of jets is arranged to direct and/or urge the cleaned aggregate to a drainage outlet.
Claims40
An apparatus for cleaning contaminated aggregate comprising:
- at least one channel arranged in use to receive a liquid containing contaminated aggregate, the at least one channel having a base comprising agitators spaced along the length of the at least one channel;
- a first bank or group of at least one nozzle;
- and
- a second bank or group of at least one nozzle;
- wherein the first bank or group of the at least one nozzle is spaced along the channel and arranged to direct jets of pressurized fluid angled in a generally downward direction to impact the contaminated aggregate in order to force the contaminated aggregate against and over the agitators along the length of the at least one channel to a first outlet thereby agitating the aggregate and promoting separation of aggregate from debris;
- and
- wherein the second bank or group of the at least one nozzle is arranged to direct and/or urge debris to a second outlet;
- wherein the base of the channel and the agitators remain stationary while the aggregate is urged along the base of the channel and over the agitators by the jets of pressurized fluid.

An apparatus for washing contaminated aggregate comprising:
- at least one channel arranged in use to receive a liquid containing contaminated aggregate, the channel having a base comprising agitators spaced along the length of the channel;
- a plurality of nozzles spaced along the length of the channel and arranged to direct jets of pressurized fluid angled in a generally downward direction to impact the contaminated aggregate in order to agitate the contaminated aggregate thereby promoting separation of aggregate from debris and contaminate and urging the aggregate over and against the agitators and through the at least one channel;
- and
- a means for removing the debris and contaminate from the surface of the liquid;
- wherein the base of the channel and the agitators remain stationary while the aggregate is urged along the base of the channel and over the agitators by the jets of pressurized fluid.

- and
- wherein the second bank or group of the at least one nozzle is arranged to direct and/or urge debris to a second outlet;
- wherein the agitators remain in substantially the same position with respect to the nozzles while the aggregate is urged along the base of the channel and over the agitators by the jets of pressurised fluid.
