ASTM D2172 Asphalt Centrifuge Extractor 3000g Capacity
Introduction:
GD-0722 Centrifuge Extractor is designed and made as per T0722-1993 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 and ASTM D2172 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.
Working Principle:
The working principle of the centrifugal extractor is based on the difference in the distribution of substances under the action of centrifugal force. When the mixture is placed in the centrifuge cup of the rotating centrifuge, the centrifugal force causes the denser substances to move to the outside of the centrifuge cup, while the less dense substances move to the center of the centrifuge cup. In this way, the substances are separated.
Centrifugal extractors are widely used in chemical laboratories and industrial production to separate and extract various compounds.
Technical features
1. Thicken aluminum alloy vessel. Stainless steel centrifugal shaft and instrument shell. Never rust .
2. Using precision machining technology, the sample container and centrifugal separator are processed precisely. After balance correction, the operation balance is stable and the asphalt separation speed is fast.
3. The instrument adopts digital display, which is intuitive and can be started up without any acceleration to ensure the smooth operation of the instrument.
4. The instrument has the advantages of fast separation, convenient operation, stable performance, light weight and convenient maintenance.
