A method of washing aggregate material, the method comprising:

• receiving aggregate material in a tank;
• receiving water in said tank;
• by at least a rear wall of said tank, retaining said aggregate material and said water in a rearward portion of said tank and preventing said water and said aggregate material from overflowing said rear wall;
• agitating said aggregate material and said water to form a slurry;
• advancing said slurry to a tank outlet in a forward portion of said tank;
• depositing said slurry through said tank outlet;
• receiving said slurry on a vibrating screen;
• vibrating said vibrating screen;
• moving said slurry across at least a portion of said vibrating screen;
• allowing an undersize portion of said slurry to fall through said vibrating screen;
• pumping at least a fraction of said undersize portion to a hydrocyclone;
• by said hydrocyclone, separating said fraction of said undersize portion into an underflow fraction and an overflow fraction;
• receiving said underflow fraction on said vibrating screen;
• and
• passing product from said vibrating screen.
