Asphalt Emulsion Plant

Feiteng’s asphalt emulsion plant is tailor-made for manufacturing emulsified common asphalt and modified asphalt, which are primarily used for slurry seals or micro-surfacing treatment.

In the emulsification process, the melted bitumen is dispersed mechanically in a solution of water stabilized with surfactant — or commonly known as emulsifying agent or emulsifier. The size of emulsified asphalt droplets is generally as small as 0.1μm.

Substances involved: melted asphalt, water, emulsifier, etc.;

Production process: with a specific ratio of asphalt and emulsifying solution, emulsified asphalt is produced by passing through a colloid mill for breaking asphalt into small droplets. Then final emulsified asphalt products will be cooled, and loaded for transportation.

Heating method: there are electric heating, thermal oil heating and oil-fired boiler for you to choose. In addition, specifically designed asphalt heating and storage tanks are also available for facilitate heating and storing asphalt, as well as produce high temperature thermal oil. It is a perfect solution for you to heat up piping circuit and water used in emulsified asphalt production process.

Features Mix proportion can be set within a range 10% to 70%; High proportional control precision, ratio error less than 1%; Emulsification equipment, as it plays core role in emulsification process, the stator and rotor of which are made of stainless steel for its strong resistance to abrasion and corrosion; All parts contact emulsifier are made of high corrosion resistant materials, which are robust and adaptable to produce emulsified asphalt with different PH values. Asphalt pump is controlled by variable frequency drive, ensuring stable operation, and accurate mixing ratio; Content detection unit is equipped to enable emulsified asphalt is qualified:
The solid content detection unit is able to display finished emulsified asphalt proportion directly without flow meter. Through three sets of temperature sensors, so asphalt temperature, emulsifier temperature, and finished product temperature can be obtained by use of dynamic solid content algorithm. High efficiency heat exchanger is equipped:
Using heat exchanger for cooling finished emulsified asphalt increases stability of asphalt storage. Simultaneously, cooling water can be re-heated for production process of emulsified asphalt. In simple terms, only first tank of water need to be heated, then water used for subsequent production processes are all heated by heat exchanger. Fully automatic controlling by PLC system;
