About Bitumen Extractor Hand Operated
A Bitumen Extractor Hand Operated is a laboratory testing instrument used to determine the percentage of bitumen in bituminous mixtures. It operates on the principle of centrifugal extraction, where bitumen is separated from aggregates using a solvent and manual rotation.
This equipment is widely used in road construction laboratories, civil engineering institutes, and quality control departments for analyzing asphalt mix composition.
Key Features
- Manual operation using hand-driven gear mechanism
- Removable aluminum rotor bowl (approx. 1500 g capacity)
- Durable cast iron / mild steel body
- Corrosion-resistant design for long service life
- Oil-bath gear system for smooth rotation
- Compact and portable for field and lab use
Technical Specifications (Typical)
- Capacity: 1.5 Litres / 1500 g
- Speed: 2400 3600 RPM (manual rotation)
- Operation: Hand Operated (Manual)
- Material: Cast Iron / Mild Steel / Aluminum
- Standards: ASTM D2172, AASHTO T-58, T-164
- Weight: ~4050 kg (varies by model)
Working Principle
The bituminous sample is placed in the rotor bowl along with a solvent (benzene/toluene). When the handle is rotated, the bowl spins at high speed, and centrifugal force separates bitumen from aggregates. The dissolved bitumen is drained out and collected for analysis.
Applications
- Asphalt and pavement testing laboratories
- Highway construction projects
- Civil engineering colleges & research labs
- Quality control of bituminous mixes
Advantages
- No electricity required (ideal for field use)
- Cost-effective compared to motorized models
- Simple operation and low maintenance
- Reliable and repeatable results
