Working Principle:
The sample mixed with solvent is placed in the rotor bowl. When rotated manually at high speed, the centrifugal force separates dissolved bitumen from aggregates, which is collected through a drain outlet for analysis.
Robust Construction and DesignCrafted from durable cast iron with a powder-coated finish, the base ensures stability and longevity. The ergonomically designed crank handle provides smooth manual operation, while the aluminum lid and bowl enhance chemical resistance and ease of use. All parts can be easily detached for thorough cleaning after use.
Efficient Bitumen ExtractionGenerating up to 3600 rpm through manual effort, the extractor provides efficient separation of bitumen from aggregate. The fitted discharge nozzle and splash guard enhance the safety and convenience of the solvent separation process, ensuring minimal mess and maximum recovery for precise results.
Versatile ApplicationsThis hand-operated centrifuge is ideal for laboratories or field environments, supporting roadway and asphalt analysis. It complies with major testing standards, making it a trusted choice for professionals in road construction and paving quality control.
FAQ's of Centrifuge Extractor Hand Operated:
Q: How do I operate the Centrifuge Extractor Hand Operated?
A: To use the extractor, load up to 1.5 kg of sample into the detachable aluminum bowl, seal it with the lockable leak-proof lid, and rotate the strong crank handle. The centrifugal force separates the bitumen, which can be collected through the discharge nozzle.
