Abstract: A washing apparatus comprises a tank in which rotatable, bladed shafts are located. The tank has a closable lower outlet located at a first end of the tank, and an upper outlet located at the first end of the tank, the upper outlet being higher than the lower outlet. A further outlet is located at a second end or between the first and second ends. The tank is disposed at an inclined angle such that the first end of the tank is lower than the second end of the tank, and is movable between a first inclined state in which the inclined angle is relatively shallow, and a second inclined state in which the inclined angle is relatively steep. The apparatus is able to perform the tasks of either a log washer or coarse material washer depending on the angle of inclination.
