MOTORISED SAND EQUIVALENT SHAKER

Motorised Sand Equivalent Shaker

Product Code  :   MSI 3014

Standard Used : ASTM D2419 | AASHTO T176 | EN 933-8 

Engineered to satisfy stringent global, British, and American standards governing the automated mechanical shaking of fine aggregate settlement cylinders.

Product Description
The Multitech Scientific Instruments MSI 3014 Motorised Sand Equivalent Shaker is a high-performance, automated laboratory testing machine designed to eliminate human error during the agitation phase of fine aggregate testing. By utilizing a precise, synchronous gear drive mechanism, this unit replicates standard-compliant reciprocating motions with perfect stroke lengths and cyclic speeds. It is widely used by geotechnical laboratories and quality-assurance engineers to quickly isolate harmful clay-like plastic fines and dust from sand fractions, providing reliable data for highway subgrades and concrete mix designs.

• Features

  • Dual-Standard Calibration: Specially configured to switch between ASTM/AASHTO and European (EN) operational stroke settings via simple linkage adjustment.

  • Zero-Slip Direct Gear Drive: Eliminates traditional drive belts, ensuring a constant, uniform rate of oscillation under heavy test loads while lowering regular maintenance requirements.

  • Integrated Precision Timer: Outfitted with an automatic digital preset controller that cuts off motor power exactly at the standard 45-second testing interval.

  • Secure Dual Clamping Assembly: Engineered with spring-loaded quick-lock brackets and base pins to hold graduated cylinders completely immobile during high-speed travel.

  • Heavy-Duty Vibration Stability: Constructed within a low-profile, solid metallic footprint that keeps benchtop vibrations to a minimum.

Application

• • Automates the agitation cycle required to derive the Sand Equivalent Value of natural sands, fine aggregate blends, and crushed rock fines.

  • Eliminates operator fatigue and tracking errors inherent in traditional, manual hand-shaking methods.

  • Essential for infrastructure project sites, commercial civil engineering testing centers, and asphalt/concrete batching plants.
