Gilson’s selection of motorized and hand-operated Sand Equivalent Shakers conform to several ASTM, AASHTO and California test standards. These units agitate samples for the Sand Equivalent Test to determine the level of undesirable clay-like fines in granular soils and fine aggregates. The mechanical shakers can also be used for evaluation of the fines portion of Durability Index Test samples.
- Motorized Mechanical Sand Equivalent Shaker is a good choice for laboratories that routinely conduct the Sand Equivalent Test. Its positive DC drive features precise speed and stroke for optimum accuracy and repeatability. The shaker is equipped with a powerful 1/8hp motor.
- Hand-Operated Spring Sand Equivalent Shaker offers economy of use, and accurate, consistent performance in measuring clay-like fines. Cylinder oscillation is manually operated to a preset mark. Stroke counts are recorded by a digital counter.
- Hand-Crank Sand Equivalent Shaker provides three cycles per crank revolution. The operator manually cranks the apparatus at one turn per second until the digital counter reaches 131 cycles. It can be mounted to a flat surface for additional stability.
