Motorized Sand Equivalent Shaker

Motorized Sand Equivalent Shaker (SL-GT-014)
ASTM D 2419, AASHTO T 176
Sand equivalent tests serve as rapid field-correlation tests to show
relative proportions of clay-like or plastic fines and dusts in granular
soils and fine aggregates. The test separates sand and clay, a
comparative reading is determined between the suspended clay and
the settled sand in the measuring cylinder. Tests may be done in the
laboratory or the field. Motorized sand equivalent shaker features
two separate electronic timers (one preset at 45 seconds and the other preset at 10 minutes) to increase accuracy and ease of
operation compared to a spring-type timer. It is recommended for
samples in the laboratory.
The consistent, repeatable oscillation of the apparatus eliminates
operator-caused variation. Shaking operation delivers an 8″
(203mm) stroke at a speed of 175 ±2 strokes per minute.
Dimensions: 12 x 24 x 24″H (31 x 61 x 61cm).
