Washers

垫圈,总

总垫圈 are used to automatically wash samples and remove particles and inconsistencies. Better results are achieved than by hand washing in the process of passing the wash water through a No. 200 sieve which prevents the loss of oversize material. Water is continuously fed into the drum and the sample is agitated until the it becomes clear, meaning that the fines have been sufficiently removed from the sample.

洪堡的 Heavy Duty 总垫圈 有15磅. (6.8kg) capacity with a 10.75” dia. X 13” D (27 x 33cm) diameter revolving drum that is designed to lock in four angle positions. Washers are available in 120V 60Hz and 220V 50Hz models.

Standard 总垫圈 are available in two sizes, one built for processing of larger aggregate and soil samples up to 15 lb. (7kg) and the other designed for washing geotechnical or smaller aggregate samples of 6-8 lb. (2.7-3.6kg). The drum is removed by swiveling the gooseneck water tube aside. Both size models come with enclosed gear motors for drum rotation and include power cords and GFCI plugs and available in both 120V 60Hz and 220V 50/60Hz.

All Humboldt 总垫圈 are designed to eliminate the high cost and time required for manual methods and conform to ASTM C535, ASTM C117 and AASHTO T11 standards. No. 200 sieves are available – sold separately.
