High Speed Extractor

Purpose:

The instrument is designed and made as per T0722-1993 and ASTM D2172 Standard Test Method for Bitumen Content of Bituminous Mixture by the Centrifuge Separation Method in Industrial Standard of People’s Republic of China JTG E20-2011 Specification and Test Methods for Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine bitumen content (bitumen-mineral aggregate ratio) in the bituminous mixture, which is made of viscous petroleum bitumen, by the centrifuge separation method. It is an ideal instrument for pavement construction units, detection unit, scientific research institutions and colleges.

I.  Main technical features

1.  Floor-type structure. It is a fully-automatic and intelligent instrument for testing the bitumen content in the bituminous mixture.

2. Micro-processing technology. Man-machine dialog. The parameter settings, working status and data are all displayed directly on the LCD. Easy to operate.

3.This instrument integrates the functions of Asphalt Extraction and solvent recovery. The solvent is used in closed-circuit circulation and has little pollution to the environment. Unique high-low-high speed extraction setting makes the collection of fine mineral powder more complete and the test results more reliable.
