Gd-0722A Automatic High Speed Centrifugal Extractor Machine for Determine Asphalt Aggregate Ratio

Function
1. Extractor asphalt content in bituminous materials
2. Determine the asphalt-aggregate ratio
3. For pavement maintenance and inspection
Standard
T0722 "Bituminous Mixture Bitumen Content Test (Centrifugal Separation Methods)"
Introduction
The high speed centifugal extractor used to extracts asphalt content in the bituminous mixture using high speed centrifugal separation methods to determine the asphalt-aggregate ratio rapidly in the bituminous mixture and it can initially screen and size aggregate.
Feature
1. It has functions of asphalt extraction and solvent recycling. The solvent is recycled in the closed system, so it is low in the pollution of the environment.
2. The rotation speed is set to high-low-high, so the mineral powder can be completely collected.
3. It uses a microprocessor for data processing. The parameters, running states, and data are shown on a LCD, so it is intuitive and it is easy to be operated.
4. The instrument has programmable run button and manually run button, so it is easy to run, maintain, or repair the instrument.
