Gravel Washer

ASTM C 117, D 1140

Aggregate samples containing clays and fines may be automatically cleaned in this washer. The inclined stainless steel drum rotates to agitate the sample as water is fed in with the goose neck tube. The overflow from the drum lip is usually passed through a No. 200 sieve until clear. The washer is driven by a sealed electric motor with reduction drive gear. The 10¾ in diameter by 13 in deep (27 x 33 cm) drum locks in four angle positions. The water supply is controlled by a valve.
