1) Main purpose
The emulsifier is the key equipment in the preparation of road modified asphalt and emulsified asphalt. In-line (continuous) high-shear emulsifier is also called emulsification pump or homogeneous pump. It integrates multi-stage emulsification and mixing, and also has the remarkable characteristics of compact structure, high efficiency and energy saving. The features of product are stable operation, strong cutting and grinding capabilities, low noise, reliable performance, long service life, safety and reliability, and low energy consumption. It is the most ideal equipment for the road modified asphalt and emulsified asphalt industry in my country.

d) Matching motor power: 18.5KW, driving mode: coupling
e) The number of teeth grinding stages and layers of the emulsifier: three levels and six layers
f) The material is 316L, acid and alkali resistant
3) Working principle and characteristics
This equipment uses a specially designed high-speed rotor and stator for precise integration. Driven by a motor, it rotates at high speed. The rotor blades drive the liquid material to rotate, forming a strong centrifugal effect. From the perspective of kinetic energy, it works on the liquid. To increase its energy. The liquid is thrown out around the stator under the action of centrifugal force. When passing through the interface of the rotor and stator, it is cut and impacted by the sharply matched and high relative speed of the rotor and stator. As the material moves forward, the cutting effect is going on continuously. At the same time, each stator slot is undergoing the same process, so that quality and output will be obtained at the same time. The liquid will obtain the first homogeneous dispersion after passing through the first stage rotor stator. After passing through the second stage two pairs of rotor stators, the refinement and dispersion effect is further strengthened. After passing through the third stage three pairs of rotor stators, emulsification and homogeneous dispersion The indicators have been greatly improved. Since the process is carried out in series, all materials will be subjected to the continuous action of three pairs of rotations and stators, so that the materials will withstand hundreds of or thousands of shearing actions, so as to ensure that the solid particles are quickly refined after the multiphase liquid highly dispersed. . When the liquid in the first-stage rotor is thrown out, a negative pressure trend is formed in the center of the rotor, thereby attracting liquid materials into the pipeline emulsifier will be continuously.
Its main features:
▷ The stator and rotor of the equipment adopt a three-level six-layer structure, and the matching gap is controlled within 0.3mm, which strongly guarantees the emulsification fineness and lays a solid foundation for the stability of the emulsified asphalt.
▷ The equipment adopts lengthened bearing chamber and Harbin bearings to ensure good clearance between stator and rotor.
▷ The flow-through part of the equipment is made of 316L stainless steel, which has higher acid and alkali resistance than other similar domestic products. The service life of the stator and rotor is guaranteed to be 10,000 hours.
▷ The equipment is driven by Siemens motor, with large torque, good reliability and high protection level, which guarantees the continuous production of emulsified asphalt.
▷ The equipment adopts mechanical seals, which are reliable in sealing. At the same time, the outlet has a certain pressure-bearing capacity and can be upgraded to emulsified modified asphalt equipment.
