Model HM-57R -Automatic Aggra-Washers
Two models automatically wash soil and aggregate samples to remove fines passing the No.200 sieve. Inconsistencies and high cost of manual methods are eliminated. 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 is directed to sieves to prevent loss of oversize material in decanted wash water. Select appropriate sizes from our extensive line of Wet-Washing Sieves. Both models are equipped with totally enclosed gear motors for drum rotation and 6ft (1.8M) power cords with GFCI plugs.
