High speed disperser, also known as mixer. According to the different lifting forms, it can be divided into hydraulic lifting disperser and mechanical lifting disperser, and the disperser speed can be adjusted arbitrarily (0-2880 rpm).

High speed disperser, also known as mixer. According to the different lifting forms, it can be divided into hydraulic lifting disperser and mechanical lifting disperser, and the disperser speed can be adjusted arbitrarily (0-2880 rpm).
Adopting various specifications such as electromagnetic speed regulation, variable frequency speed regulation, and three speed regulation, stable and powerful operation, suitable for various viscosities; Hydraulic and mechanical lifting modes, lifting and rotating freely, suitable for various positions; Ordinary and explosion-proof configuration, safe and reliable, easy to operate and maintain; Strong production continuity, fast dispersion and dissolution of materials, good dispersion effect, high production efficiency, stable operation, and easy installation. There are different powers and models for the viscosity and processing capacity of different materials.
1、 The disperser adopts stepless speed regulation: there are various forms such as electromagnetic speed regulation, variable frequency speed regulation (such as for water-based coatings), and explosion-proof variable frequency speed regulation (such as for oil-based coatings). The stepless speed regulation function can fully meet the different process requirements in each process, and different speeds can be selected according to different process stages. Materials with no additives added to the powder and high requirements for crystal package integrity are not suitable.
2、 The dispersion tray of the disperser is in a laminar flow state, and the slurry layers with different flow rates diffuse with each other, playing a dispersing role. The high-speed disperser has various functions such as hydraulic lifting, 360 degree rotation, and stepless speed regulation. It can be equipped with 2-4 containers at the same time, with a hydraulic lifting stroke of 1000mm and a 360 degree rotation function, which can better meet the needs of one machine for multiple purposes. It can switch from one cylinder to another in a short time for operation, greatly improving work efficiency and reducing manual labor intensity.
3、 The disperser forms a turbulent zone at a distance of 2.5-5mm from the edge of the disperser disk, and the slurry and particles are subjected to strong shear and impact.
4、 The disperser is mainly used for crushing, dispersing, emulsifying, and mixing liquid raw materials with different viscosity slurries. Through a new type of high-efficiency mixing equipment that operates at high speed with serrated upper and lower teeth on the disperser plate, the material is subjected to high-speed and intense shearing, impact, crushing, and dispersion, achieving the function of rapid mixing, dissolution, dispersion, and refinement. Feed area, while suction into the working chamber from the axial direction.
The high-speed disperser has a wide range of applications, complete functions, and multiple functions. It was developed due to the continuous development of industry.
High shear dispersion is the process of efficiently, quickly, and uniformly transferring one or more phases (liquid, solid, gas) into another immiscible continuous phase (usually liquid). Under normal circumstances, each phase is immiscible to each other. When external energy is input, the two materials recombine into a homogeneous phase. Due to the strong kinetic energy brought by the high tangent speed and high-frequency mechanical effect generated by the high-speed rotation of the rotor, the materials are subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tear and turbulence in the narrow gap between the stator and rotor, forming suspension (solid/liquid), lotion (liquid/liquid) and foam (gas/liquid). Thus, the immiscible solid, liquid, and gas phases are uniformly and finely dispersed and emulsified in an instant under the combined action of corresponding mature processes and appropriate additives. After high-frequency cycling, stable and high-quality products are ultimately obtained.
