Gilson’s two Aggregate Washer or "Agg Washers" models automatically wash soil and aggregate samples by removing fines passing through the No.200 sieve, eliminating inconsistencies, and the high cost of manual methods.
Water is continuously fed into the revolving, inclined stainless steel drum via a permanent regulated connection, and the sample is gently agitated until overflow is clear. Overflow water is directed onto sieves to prevent loss of oversize material.
Models are equipped with completely enclosed gear motors for drum rotation and 6ft (1.8M) power cords with GFCI plugs. The fixed-angle removable drum can be used as a weighing container. Gooseneck water tube swivels aside to allow drum removal. Both models are portable and convenient for placement on a countertop adjacent to a sink.
Small Automatic Aggregate Washer is useful for washing geotechnical or small aggregate samples of up to 6—8lb (2.7—3.6kg). Order extra drums to improve sample processing efficiency. The stainless steel drum is 9in diameter x 10.75in high (229x273mm).
