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 water in a rearward portion of said tank and preventing said water and aggregate material from overflowing said rear wall; agitating said aggregate material and 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; 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.

Aggregate washing systems, methods, and apparatus

Aggregate washing systems are described including mechanisms for slurrying, washing and/or dewatering aggregate material. Some embodiments include a slurry mixer having a tank, water inlet and propulsion assembly. Some embodiments include a dewatering mechanism having a vibrating screen.

Hydrocyclones and related apparatus, systems and methods are disclosed for classifying aggregate material. Some embodiments include an inlet head with a spiral inlet having a height and width that vary along the direction of travel of material in the inlet head. Plants incorporating hydrocyclones are disclosed for classifying aggregate material. Some plant embodiments include an overflow container having a weir.

Classifying apparatus, systems and methods

Hydraulic classifiers are provided for sorting material using injected water. Some embodiments include upper and lower housings having different cross-sectional shapes. In some embodiments, certain improvements are provided for cleanout and/or removal or replacement of teeter bars.
