Gilson Large Laboratory Aggregate Washer

Gilson Aggregate Washers or "Agg Washers" assist in separating No.200 (75µm) and smaller fines from soil and aggregate samples. Its consistent rotating motion helps eliminate inconsistencies in the washing process and is less costly than laborious 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 the 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. The Gooseneck water tube swivels aside to allow drum removal. Both models are portable and convenient for placement on a countertop adjacent to a sink. HM-57R Aggregate Washer allows the processing of large aggregate samples up to 15lb (7kg). The stainless steel drum is 12x11in (304.8x279.4mm), IDxH. Extra drums can be ordered as HMA-261 to improve sample processing efficiency.
