Aggregate Washer 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 through a flexible gooseneck nozzle with a regulated connection. The sample is gently agitated until overflow is clear. Overflow is directed to sieves to prevent loss of oversize material in decanted wash water. Removable drums can be used as weighing containers.

Both Aggregate Washer models incorporate vinyl tubing for a connection to a standard water line or faucet with user applied adapter to provide sufficient water supply for the aggregate washing process. The water continuously flows into the revolving wash drum and washes the aggregate sample. The constant washing creates an aggregate and water mixture that overflows from the wash drum and into a No. 200 (75µm) sieve. For more information on how this process works, check out our blog post, How to Optimize Fines Content Determinations.

Stainless steel drum size is 11in diameter x 13in high (279x330mm). Extra drums can be ordered as HMA-261 to improve sample processing efficiency.
