LS-EXT-D Digital Centrifuge Extractor
LS-EXT-D Digital Centrifuge Extractor is a asphalt content ignition furnace and asphalt extraction equipment for ASTM D2172, AASHTO T164 workflows. High-capacity digital centrifugal extractor for quantitative binder recovery using the centrifuge separation method as per ASTM D2172 and AASHTO T164. Ideal for determining asphalt content (or binder-aggregate ratio) in viscous petroleum asphalt mixtures for pavement construction quality control and in-service road condition surveys. Features an advanced vibration-dampening architecture with internal counterweighting for ultra-smooth, stable operation and a programmable soft-start motor.
4.3" HD Color LCD Interface
Equipped with a high-definition 4.3-inch color LCD panel providing comprehensive real-time visualization of centrifuge speed, elapsed time, and animated operational status — delivering full process transparency at a glance.
Direct-Drive Anti-Vibration Architecture
Utilizes an extended-shaft motor with direct-drive coupling and a dual-spring vibration dampening system (upper and lower) to effectively eliminate concentricity deviation, significantly reducing whole-machine vibration amplitude for safer, quieter operation.
Integrated Counterweight Stability System
Features a factory-installed base counterweight that lowers the center of gravity, allowing the unit to be placed directly on a stable concrete floor or benchtop foundation without the need for external anchoring or anti-vibration pads.
Programmable Soft-Start Motor Control
The intelligent soft-start system gradually ramps the centrifuge speed from zero, protecting the motor and drive train from inrush current damage while ensuring the asphalt-solvent mixture is accelerated smoothly without sudden mechanical shock.
